Potassium hydroxide
KOH
Potassium hydroxide (KOH) is a strong base that is commonly used in various laboratory and industrial applications. It is a white, odorless, and highly caustic solid that is soluble in water, alcohol, and glycerol.
Some of the common uses of potassium hydroxide include:
1. Soap making: KOH is used to make liquid and soft soaps, as it reacts with fatty acids to form potassium salts of these acids.
2. Catalyst: KOH is often used as a catalyst in various chemical reactions, such as the synthesis of biodiesel from vegetable oils.
3. Cleaning agent: KOH is used in some cleaning agents due to its ability to dissolve and emulsify oils and fats.
4. Electrolyte in batteries: KOH is used as an electrolyte in some types of batteries, such as alkaline batteries.
5. Food processing: KOH is used in some food processing applications, such as removing skins from fruits and vegetables.
However, it is important to handle potassium hydroxide with caution, as it can cause severe burns on contact with skin and eyes. It is also important to keep it away from other acids and reactive chemicals, as it can react violently with them.
