potassium carbonate crystals

[Colin Graham]

Can anhydrous be substituted for this? Or if not does any one know of a source for the crystal form? Thanks

I think the only difference between the anhydrous and crystal is the water content; the crystal having some and the anhydrous having none.

Bookmark this site and have a look; sorry I am crushed for time!

Thanks, Frank, but no site seems to have the conversion for anhydrous to crystal for Potassium Carbonate.

The CRC Handbook of Chemistry and Physics lists K2CO3 and K2CO3.2H2O. The ratio of molecular weights is 1.261, so you would need 1.26 times as much by weight of the crystalline as of the anhydrous to get the same amount of carbonate.

Ah...I was hoping you might stop by! Thanks very much indeed.
