➡ the metal nitrate is a salt which gives yellowish brown colour on heating
➡ a crackling sound is heard and the salt decripitates
➡it is necessary to know that lead oxide (PbO) has a yellowish brown colour on heating the nitrate
➡ brown fumes may also come out from the test tube
➡since the salt is a nitrate - the name of the salt is lead nitrate
i.e. Pb(NO3)2
and the above reaction is:-
2Pb(NO3)2 -------> 2 PbO + 4NO2 + O2 ⬆
