Question

What happens when lead (II) nitrate is heated?

Write balanced chemical equation of the reaction involved in support of your answer.

Answer 1

\[\ce{2Pb(NO3)2 (s) \overset{\triangle}{->} 2PbO(s) + 4NO2(g) + O2(g)}\]

When lead (II) nitrate powder is heated in a boiling tube, it decomposes to form lead (II) oxide, nitrogen dioxide gas, and oxygen gas. You will observe brown nitrogen dioxide fumes and a yellow residue of lead oxide.
