Which solid product is formed on thermal decomposition of lead nitrate?
Answer and explanation
Correct answer: Lead oxide
On heating, lead nitrate undergoes thermal decomposition: \(2\mathrm{Pb(NO_3)_2} \xrightarrow{\Delta} 2\mathrm{PbO} + 4\mathrm{NO_2} + \mathrm{O_2}\). Lead oxide is the yellow solid formed, while nitrogen dioxide and oxygen are released as gases. Therefore, lead sulphate, lead chloride, and lead carbonate are not products of this reaction.
