Physicsfan Posted June 21, 2010 Share Posted June 21, 2010 Why dont they react? Link to comment Share on other sites More sharing options...
Fuzzwood Posted June 21, 2010 Share Posted June 21, 2010 Because ammonium nitrate and calcium hydroxide are also very soluble salts. Link to comment Share on other sites More sharing options...
John Cuthber Posted June 21, 2010 Share Posted June 21, 2010 Calcium hydroxide isn't very soluble; they should react. (Technically NH4OH doesn't exist) Link to comment Share on other sites More sharing options...
Physicsfan Posted June 22, 2010 Author Share Posted June 22, 2010 (Technically NH4OH doesn't exist) Its a solution of ammonia in water. I guess calcium hydroxide reacts with ammonium nitrate to give ammonia? Link to comment Share on other sites More sharing options...
John Cuthber Posted June 22, 2010 Share Posted June 22, 2010 "Its a solution of ammonia in water." No, it's not. On warming a solution of ammonium nitrate with calcium hydroxide I would expect to get ammonia, but with reasonable concentrations of ammonia solution and calcium nitrate I would expect a precipitate of calcium hydroxide. It's certainly an equilibrium reactions so it could go either way depending on the conditions. Link to comment Share on other sites More sharing options...

If not, then it cannot be a equilibrium reaction i.e go wither way...this is my understanding. Edited June 22, 2010 by Nerddoc Link to comment Share on other sites More sharing options...
John Cuthber Posted June 23, 2010 Share Posted June 23, 2010 It is slightly soluble, a couple of grams per litre IIRC. Link to comment Share on other sites More sharing options...

Shristi Posted February 16, 2018 Share Posted February 16, 2018 The concentration of OH- ions from the ionisation of NH4OH is so low that it can not precipitate the hydroxide of calcium Link to comment Share on other sites More sharing options...
