The oxide of nitrogen evolved by heating lead nitrate is passed through ferrous sulphate solution .state your observation
Dear student
When lead nitrate is heated strongly, NO2 and O2 are given out.
2Pb(NO3)2 (s) ------> 2PbO (s) + 4NO2 (g) + O2 (g)
The colourless lead nitrate converted to a yellow compound, lead monoxide, and brown fumes of nitrogen dioxide gas are evolved.
The reddish brown NO2 turns freshly prepared FeSO4 brown due to formation of FeSO4.NO.
