Question

What do you observe when Lead (II) nitrate is heated? Write minimum two observations.

Answer 1

Answer:

Lead nitrate on heating decomposes to lead monoxide, nitrogen dioxide and oxygen. 2Pb(NO3)2 = 2PbO + 4NO2 + O2. NO2 is liberated, along with oxygen, as a reddish brown gas. The residue left is lead monoxide.
