When a solution of nitric acid is added to a to solution of calcium hydroxide, the salt formed has what formula?
SpyIntel [72]


Nitric acid and calcium hydroxide react to form calcium nitrate and water.

The molecular equation is as follows:

2HNO3 (aq) + Ca(OH)2 (aq)  = Ca(NO3)2 (aq) + 2H2O (l)

So the formula of calcium nitrate, the salt formed in this reaction is Ca(NO3)2 .

Water here seem to be the only real product. It is formed from the OH+  of the hydroxide and the H+ of the acid which combine to form two water molecules.

Calcium and Nitrate ions remain unchanged before and after the reaction and are thus known as spectator ions.
