Reactions of group (IV) elements with nitric acid

With concentrated nitric acid.

C, Si, Ge and Sn react to form dioxide

C(s) + 4HNO₃(aq)→ CO₂(g) +4NO₂(g) + 2H₂O(l)

Pb reacts to form lead II nitrate and nitrogen dioxide.

Pb(s) + 4HNO₃(aq)  →  Pb(NO₃)₂(aq) + 2NO₂(aq)+ 2H₂O(l)

With 50% nitric acid.

Pb reacts to form lead II nitrate and nitrogen monoxide.

3Pb(s) + 8HNO₃(aq)  → 3Pb(NO₃)₂(aq) + 2NO(aq)+ 4H₂O(l)
