What is the identity of the brown gas formed on heating lead nitrate?

Answer and explanation

Correct answer: Nitrogen dioxide

On heating, lead nitrate undergoes thermal decomposition: 2Pb(NO₃)₂ → 2PbO + 4NO₂ + O₂. The nitrogen dioxide produced is a reddish-brown gas, so option A is correct. Oxygen is also formed in the reaction but is colourless. Hydrogen and carbon dioxide are not products of lead nitrate decomposition.
