Which yellow solid residue is formed on thermal decomposition of lead nitrate?

Answer and explanation

Correct answer: Lead(II) oxide

On heating, lead nitrate undergoes thermal decomposition: \(2\mathrm{Pb(NO_3)_2} \xrightarrow{\Delta} 2\mathrm{PbO} + 4\mathrm{NO_2} + \mathrm{O_2}\). The yellow solid residue is lead(II) oxide, \(\mathrm{PbO}\). In contrast, lead(II) chloride contains chloride ions, which cannot be formed by merely heating lead nitrate.
