POTASSIUM CARBONATE ANHYDROUS
Potassium carbonate is a potassium salt that is the dipotassium salt of carbonic acid. It has a role as a catalyst, a fertilizer and a flame retardant
Potassium carbonate is a potassium salt that is the dipotassium salt of carbonic acid. It has a role as a catalyst, a fertilizer and a flame retardant. Potassium carbonate anhydrous, K2CO3 anyydrous, appears as a white powder or as colorless solid crystal that is void of water and has a salty taste. ... It also used in fire extinguishers, to make soap, to make glass, and to soften water.

Description
Potassium carbonate (K2CO3) is a white salt, soluble in water (insoluble in ethanol) which forms a strongly alkaline solution. It can be made as the product of potassium hydroxide's absorbent reaction with carbon dioxide.
