2CaCO3 +NH4 ---- 2Ca + (NH4)2CO3 Is this possible?
« on: April 26, 2010, 04:19:58 PM »
I am trying to determine if Calcium Carbonate and Ammonium can react. If this reaction were possible would it need heat to start it?

2CaCO3 + NH4 ----2Ca + (NH4)2CO3

If this isn't correct are there any other results that could be a result of CaCO3 and NH4 reacting?

What solvent are you using? Calcium carbonate is a solid and ammonium is a dissociated ion. To have any reasonable expectation of reaction both must be in the liquid phase which requires a solvent. So you must consider solubilities and reactivity with the solvent.

The solvent would be water. Sorry about excluding that.

If water's the solvent, then I think the reaction would be :

CaCO3 + 2NH4OH ---> Ca(OH)2 + (NH4)2CO3

2CaCO3 + NH4 ----2Ca + (NH4)2CO3

This reaction is impossible. Moreover this is wrong reaction from stoichiometric point of view.
