stating uses for it would be helpful. like making tyedye shirts.

It is also use as an acidity regulator; but that's all I know. ^KILO-_LIMA 13:58, 26 February 2006 (UTC)[reply]

Soda ash is commonly used to raise the Ph in swimming pools and spas.

I think the staments in the artical concerning the usaes of Sodium Carbonate in photography are misleading and inaccurate. The primary use of Sodium carbonate in photography is in B&W film developers. It is (or was) commonly used as the alkali which is necessary to activate the developing agent.

I'd like to ask: If it were heated, would it not transform to to carbon dioxide and sodium oxide?

Thats what i would have thought, but when i heated Sodium Bicarbonate until it decomposed into sodium carbonate then treated it with 12 molar HCl giving me something that ressembled Calcium Sulfate (plaster of paris). Any thoughts??

Heat sodium bicarbonate until it decomposes fully into sodium carbonate. Then heat it some more, see if it decomposes. THEN, if it does, put it in a solution of baker's ammonia ((NH₄)₂CO₃). If this makes it reek of ammonia, then you have put something basic in it, which would indicate that you put Na₂O in it. I'd try it myself, but I have improper heating devices.

Also used for dyeing fabrics

Would any of you chemists be able to include some of this info on this page? http://www.pburch.net/dyeing/FAQ/sodaash.shtml
