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

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.
