Potassium Carbonate Product Name Potassium Carbonate CAS No. 584-08-7 Molecular Weight138.21 Structural Formula K2CO3 Description: It is monoclinic crystal, white powder, granular crystal or prill. It is easily soluble in water forming a slightly alkaline solution and insoluble in alcohol and ether. It has strong hygroscopicity. It easily cakes and turns into Potassium Bicarbonate through absorbing carbon dioxide when exposed to the air for a long time.
