Nitric acid (HNO₃) reacting with calcium hydroxide (Ca(OH)₂) produces:

* Calcium nitrate (Ca(NO₃)₂) - a white, soluble solid

* Water (H₂O)

The balanced chemical equation is:

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

This reaction is a neutralization reaction because an acid (nitric acid) reacts with a base (calcium hydroxide) to form a salt (calcium nitrate) and water.
