Physical properties

• Appearance : White flaky or lumpy solid.

• Solubility : Very soluble in water, releasing a large amount of heat; also soluble in ethanol, slightly soluble in ether.

• Hygroscopicity : It readily absorbs moisture from the air and deliquesces, and absorbs carbon dioxide to form potassium carbonate.

• Corrosiveness : It is highly corrosive, reacts with water and water vapor to release heat, and its solution is strongly alkaline. 

• A typical strong base, it can undergo a neutralization reaction with acids.

• It can react with carbon dioxide.

• It can participate in reactions such as nucleophilic substitution and hydrolysis. 

• Chemical industry : Production of various potassium salts such as potassium permanganate and potassium carbonate.

• Daily chemical products : manufactures potassium soap, shampoo, cold cream, etc.

• Pharmaceuticals : Used in the production of various drug components.

• Batteries : Manufacturing electrolytes for alkaline storage batteries.

• Textiles/Leather : Printing, dyeing, bleaching, and leather degreasing.

• Electrochemistry : electroplating, engraving, etc.

• Other uses : as a desiccant, absorbent, analytical reagent, pH adjuster, etc. 

• It is highly corrosive; protective equipment must be worn during operation to avoid contact with skin, eyes, and inhalation of dust.

• It should be stored in a well-ventilated, cool, and dry warehouse, and kept separate from flammable materials and acids.
