A White salt upon heating decomposes to give brown fumes and a residue is left behind.
(i) Name the salt.
(ii) Write the equation for the decomposition reaction.

Text Solution

Verified by Experts

The salt is lead nitrate. The decomposition reaction is
`underset(("White"))underset("Lead nitrate")(2Pb(NO_(3))_(2(s)))overset("Heat")tounderset(("Yellow"))underset("Lead oxide")(2PbO_((s)))+underset(("Brown fumes"))underset("Nitrogen dioxide")(4NO_(2(g)))+underset("Oxygen")(O_(2(g)))`
