Name the compound. The salt which on thermal decomposition leaves a coloured residue, liberated a reddish brown gas and a colourless gas. The residue reacts with caustic soda to give sodium plumbite.
Correct Answer: 0
PLACEHOLDER ANSWER - the answer is a name. The salt is lead nitrate, $$2\text{Pb(NO}_3)_2 \rightarrow 2\text{PbO} + 4\text{NO}_2 + \text{O}_2$$. The yellow residue PbO dissolves in NaOH as sodium plumbite, $$\text{PbO} + 2\text{NaOH} \rightarrow \text{Na}_2\text{PbO}_2 + \text{H}_2\text{O}$$.
