Question

Give two uses of potassium hydroxide​

Answer 1

Answer:

Potassium hydroxide, also called caustic potash, is a chemical compound with the formula KOH. The purified material is a white solid that is commercially available in the form of pellets and flakes. Similar to sodium hydroxide (caustic soda, NaOH), it is a strong alkali, very soluble in water, and highly corrosive. It is useful for a variety of applications, including the manufacture of soaps, biodiesel, batteries, fuel cells and fertilizers.

Preparation of Salts

Being strongly alkaline, potassium hydroxide reacts with various acids, and this acid-base reaction is used for the production of potassium salts. These salts, in turn, have a number of different applications. For example, the phosphates of potassium are fertilizers, the carbonate is used in the manufacture of soap and glass, the cyanide is used in gold mining and electroplating, and the permanganate is a disinfectant.

Neutralization of Acids

As an alkali, potassium hydroxide is used to neutralize acidity and adjust the pH of solutions. In chemical analyses, it is a valuable agent for the titration of acids to determine their concentration.
