Chemical Properties Of HNO3

1. Neutralizaion-
HNO_3(aq) + NaOH_(aq)  →    NaOH_3(aq) + H₂O_(L)

2. It reacts with trioxonitrate (iv)
2HNO_3(aq) + CaCO_3(s)  →   Ca(NO₃)_2(aq) + H₂O_(L)+ CO_2(g)

3. It reacts with highly electropositive metals to form trioxonitrate
Mg_(s) + 2HNO_3(aq)   →    Mg(NO₃)_2(aq)+H_2(g)

It is a powerful oxidizing agent.
