Lead nitrate on heating gives
General KnowledgeChemistry
- APbO and NO
- BPbO and NO 2 2 2
- CPbO and NO
- DPbO and NO 2
Explanation
On heating, lead nitrate decomposes as: 2Pb(NO3)2 gives 2PbO plus 4NO2 plus O2 — yielding lead oxide and nitrogen dioxide (brown fumes). It does not yield PbO2 or NO. The correct products are PbO and NO2.
