Product Name

Potassium Carbonate

CAS No.

584-08-7

Molecular Weight

138.21

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.
