In thermal decomposition of lead nitrate the yellow solid residue is of which substance?

Answer and explanation

Correct answer: Lead oxide

Lead nitrate decomposes on strong heating according to 2Pb(NO₃)₂ → 2PbO + 4NO₂ + O₂. Nitrogen dioxide escapes as a brown gas and oxygen as a colourless gas, leaving lead oxide as the solid residue. Lead oxide is yellow when hot and may appear differently on cooling. Chloride, sulphate, and carbonate residues require other anions and are not formed here.
