Assertion : Brown fumes are produced when lead nitrate is heated.
This is true.
When lead nitrate is heated strongly, NO2 and O2 are given out.
In this decomposition reaction, the colourless compound lead nitrate forms a yellow compound, lead monoxide, and brown fumes of nitrogen dioxide gas are evolved.
Reason: Nitrogen dioxide is produced as a by product due to the decomposition of lead nitrate.
This is true.
2 Pb(NO3)2 → 2 PbO + 4 NO2 + O2
Both Assertion and Reason are correct and Reason explains the assertion.
Option A is correct.
