What is Potassium Hydroxide?

Potassium hydroxide is a chemical that exists in powder, flake, or pellet form. Commonly known as licking or potash. It is a caustic chemical. Potassium hydroxide solution is a strong mineral liquid that acts as a strong base. This solution has many uses. Chlorine and hydrogen are used during the process of producing potassium hydroxide.

History of potassium and potassium hydroxide

Until the 18th century, there was no distinction between potassium and sodium. This was because early chemists did not recognize that mineral alkalis (from earth's sediments, sodium carbonate) and plant alkalis (derived from chulch ash, potassium carbonate) were distinct from each other. But eventually this distinction happened. Before potassium was recognized as an element, a mixture of potassium carbonate and animal fat was used to make soap. Potassium was isolated in 1807 by Sir Humphrey Davy, and potassium hydroxide was obtained by electrolysis of potash. Potassium is collected from the cathode, and is also the first metal to be separated by electrolysis.

Structure and formula of potassium hydroxide

The chemical formula of potassium hydroxide is KOH. The structure of KOH consists of an ionic bond between anion and a hydroxyl cation.

Physical features

Potassium hydroxide is a white solid with a density of 2,044 g / ml, a melting point of 360 ° C and a boiling point of 1,327. It is usually available as clear pellets or aqueous solutions of various concentrations.

Chemical properties

Potassium hydroxide is a highly moist solid that absorbs water from the air, making it a useful laboratory desiccant. It is thermally stable (does not decompose even at high temperatures). This substance dissolves in water and a highly alkaline aqueous solutions are formed called potassium sludge. It reacts easily with acids to form potassium salts that have many applications in industry.

 PH of potassium hydroxide


KOH is an example of a strong base, you can use this compound as 100% split into hydroxide ions in solution. This means that it dissolves into its ions in aqueous solution. Although the pH of KOH or potassium hydroxide is very high (usually between 10 and 13 in normal solutions), its exact value depends on the concentration of this strong base in water. Therefore, it is important to know how to calculate the p.


Strong base pH

 Potassium hydroxide is a strong base in terms of chemical ionization, and its solutions can be measured using a strong acid such as hydrochloric acid or sulfuric acid or using an acidic standard such as potassium hydrogen phthalate (KHP). Typical neutralization reactions include: KOH + HCl → KCl + H 2 O KOH + KHPhthalate → K 2 phthalates + H 2 O The end point can be determined using a number of pH indicators by changing the color at any point in the pH range 3 - 10.5.
The choice of index used depends on the initial concentration of potassium hydroxide and the strength of the acid used. This is because acid and base habits affect the shape of the neutralization curve that results during titration. When both the acid and the base are normal in concentration 1, indicators with an effective range between pH 3 and 10.5 can be used. Suitable indicators include methyl orange, green bromocrozole, methyl red, methyl purple, blue bromothymol, red phenol, phenolphthalein and thymolphelalin. When both acid and base are normal, the ideal pH range is reduced to 4.5 to 9.5. Therefore, methyl orange and thymolphelaine are not as suitable as others. With 0.01 g of normal solution, the ideal pH range is further limited to 5.5 - 8.5.

Potassium hydroxide problems on the skin

At high concentrations, potassium hydroxide can aggravate the skin, even if used in washing products such as soaps or cleansers. In fact, using an alkaline cleanser, even once, can cause significant damage to the skin.

Alkaline cleansers alter the composition of the skin's natural bacterial flora and the activity of enzymes in the upper layers of the skin, because these two have optimal pH levels. In addition, the damage is cumulative. The longer you use the product, the more damage it will do to your skin.

Health effects / safety hazards

Potassium hydroxide is a strong base that can penetrate the skin and tissues. Skin and eye contact with KOH solution can cause burns, severe irritation and even blindness. Inhalation of this substance also damages the mucous membranes and lungs. KOH solution is very toxic and deadly if swallowed and can lead to permanent tissue damage.

Challenges of potassium hydroxide

When potassium hydroxide is dissolved in water or neutralized with acid, it releases a significant amount of heat. If not done properly, it can cause a severe, exothermic reaction that ignites flammable materials.

Uses of potassium hydroxide or potassium hydroxide

Chemical is a major industry that is used as a base in a wide range of chemical processes.

The most used in the production of potassium carbonate, potassium phosphates, liquid fertilizers and soaps and detergents are potassium. The largest single use is in the production of potassium carbonate, which is mainly used in the manufacture of special glasses, including television tubes.

Potassium hydroxide is used in agriculture to modify the pH of acidic soils. It can also be used as a fungicide or even herbicide. Used in the production of agricultural fertilizers. These fertilizers can be used as a source of potassium (one of the three main plant foods) for products that are sensitive to chloride ions.

Used as a substitute for caustic soda in the production of biodiesel.

Some applications of KOH include acrylate ester copolymer coating, anti-foaming agents in paper making, liquid soap making oils, food formulations, pH control agent, polyethylene resins, textile processing and as a catalyst in reactions such as Biodiesel production.

Other uses in veterinary medicine are in separating calf horns and dissolving scales and hair. In human medicine, it is used to diagnose fungal infections and as a wart and cuticle solvent and to make cleansers. These compounds are also used in toothpastes, some dentures, non-phosphates, and drain or tube cleaners.

A very significant use of potassium hydroxide, in terms of importance in alkaline batteries use aqueous solution of KOH as an electrolyte. Therefore, potassium hydroxide helps power flashlights, smoke detectors, and other battery-powered appliances.

It is also an anisotropic silicon pen that exposes octagonal plates. This method can create etches on a regular basis for applications such as micro-electromechanical systems, pyramids and holes.

The final applications of potassium hydroxide or potassium hydroxide include plating, herbicides, greases, catalysts, oxidizers, drugs and alkaline-electrolytic batteries. Potassium hydroxide is used as a direct intermediate for several potassium chemicals, including potassium cyanide, aluminate, formate, flosilica, borohydride, bromate, bromide, gluconate, lorate, manganese, oleate, and titanate.

Applications of potassium hydroxide

Potassium hydroxide solution has many applications in various industries. From food and skin care products and medicines to agriculture and glass production. Electrolyte is also used in the manufacture of batteries and some airport runways. In addition, KOH is used in the manufacture of skin care products such as body lotions, soaps and shampoos. Potassium hydroxide is also used in liquid fertilizer due to its high solubility and low salt content.

Potassium hydroxide as a cleanser

Potassium hydroxide is a very diverse cleaning agent. For example, potassium hydroxide is found in a variety of items such as liquid soaps, lotions, shampoos, sprays, and dentures. It is mostly used in industrial compounds such as stove cleaners, drain cleaners, road and concrete cleaners, detergents and in drain and pipe cleaners.

While the use of sodium hydroxide for soap is common, potassium hydroxide soaps are actually more soluble in water and better for the environment. Potassium hydroxide soaps are also known as "soft soaps". Although not as popular as sodium soaps, potassium soaps are produced in varying concentrations of liquid and are often used in combination with sodium soaps, for example in shaving products as well as in the textile industry.

Potassium hydroxide as a pH regulator

Potassium hydroxide is a strong alkali or base, and many uses are the result of this property. It acts as a base, pH regulator in industrial manufacturing and processing. Potassium hydroxide is used in agriculture to regulate the pH of acidic soils.

Potassium hydroxide in medicine

It also has medicinal uses. In veterinary medicine, potassium hydroxide is used to separate calves' horns and to dissolve scales and hair. In humans, it can be used to diagnose fungal infections. It can also be used to dissolve warts and cuticles.

Potassium hydroxide in food

Potassium hydroxide is often found as an additive in commercial processed foods and as a detergent or chemical peel for fruits and vegetables. It is added to processed foods as a stabilizer to increase shelf life and as a thickener. It is involved in the processing of chocolate and cocoa, the processing of soft drinks and the thickening of ice cream. Potassium hydroxide is used to soften olives and glaze salt wood before cooking to make them crispy.

Miscellaneous applications of potassium hydroxide

Potassium hydroxide acts as a foaming agent in the paper production process. Potash is an excellent pH regulator and is therefore used on farms to regulate the pH balance of acidic soils. It is also used as a grass food, industrial fertilizer, fungicide and herbicide. Heated potassium hydroxide is commonly used for mass etching of silicon wafers, which is important in the manufacture of some microelectronic devices.

Potassium hydroxide solutions

Potassium hydroxide solutions corrode aluminum and its alloys due to the formation of hydrogen gas. This corrosion can be prevented by adding potassium salts related to acids.

In corrosion behavior and safety requirements, potassium hydroxide is very similar to sodium hydroxide (NaOH). Although potassium hydroxide is slightly more aggressive, it is generally associated with a higher boiling point and the possibility of exposure to higher temperatures.

Nickel alloys in sodium hydroxide are less sensitive to stress cracking in potassium hydroxide. Plastics and coatings show the same resistance to potassium hydroxide and sodium hydroxide, except for fiberglass-reinforced plastics, which are less resistant to potassium hydroxide, regardless of the type of resin used.

Most people use this solution in their daily lives. For example (from batteries to fertilizers and soaps). It helps to neutralize acid as a strong base, it can also be used as a thickener and food stabilizer. Potassium hydroxide has medicinal properties for both humans and animals and represents many industrial processes.

Similarities and differences between potassium hydroxide and sodium hydroxide

Potassium hydroxide and sodium hydroxide are remarkably similar and can often be used in the same applications. In soap making, they are used in the process of converting fats into soap. Likewise, both compounds can be used to make biodiesel. However, despite their similarities, there are a few cases in which you can not exchange one for another. For example, potassium hydroxide is used as an electrolyte in alkaline batteries and sodium hydroxide in water treatment.Of all the compounds in the hydroxide group, potassium hydroxide and sodium hydroxide are the most chemically similar. Chemical reactions are completely consistent with the physical appearance of solids and liquids and their behavior, allowing them to stand together in different situations.Their differences start at the molecular level. Potassium hydroxide is slightly smaller than sodium hydroxide, meaning it transports oil molecules faster than sodium hydroxide.This makes potassium hydroxide a good choice for soaps that need to remove cake oil. It also releases slightly less heat than sodium hydroxide when exposed to water.The world consumes 700,000 to 800,000 tons of the compound annually.
