A student while heating solid lead nitrate taken in a test-tube would observe :
(1) white residue of PbO2
(2) green residue of NO2
(3) yellow residue of PbO
(4) brown residue of NO
Open in App Solution
When lead nitrate is heated, a yellow residue of lead oxide is obtained, and brown colored gas is liberated, i.e. nitrogen dioxide.
2Pb(NO3)2→2PbO+4NO2+O2
Hence, the correct answer is option 3.
