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.
It is deliquescent, often appearing a damp or wet solid.
Potassium carbonate is used in the production of soap and glass.
