Potassium Carbonate

Potassium Carbonate may be monoclinic crystal, white powder, granular crystal or prill. The relative density is 2.428 and the melting point is at 891 degree C Potassium Carbonate is easily soluble in water forming a slightly alkaline solution. It is insoluble in alcohol and ether. Potassium Carbonate has strong hygroscopicity. It easily cakes and turns into Potassium Bicarbonate through absorbing carbon dioxide when exposed to the air for a long time.
