Question

What happens when?
Red lead is treated with nitric acid.

Answer 1

Red lead is a mixture of oxides. The following reaction occurs when red lead is treated with nitric acid.

$P{b}_3{O}_4⟶2PbO+Pb{O}_2$ ------ 1

$[PbO+2HN{O}_3⟶Pb(N{O}_3{)}_2+H_{2}O]\times 2$ ------ 2

Overall reaction:

$P{b}_3{O}_4+4HN{O}_3⟶2Pb(N{O}_3{)}_2+Pb{O}_2+2H_{2}O$
