A red crystalline solid A reacts with nitric acid to form a chocolate-brown solid B insoluble in water. Both A and B reacts with HCl to form `PbCl_(2)`. A and B respectively areA. `PbO,PbO_(2)`B. `Pb_(3)O_(4),PbO_(2)`C. `PbO_(2),Pb_(3)O`D. `PbO_(2),PbO` |

Answer» Correct Answer - B The reaction involved are `underset("(A)")(2Pb_(3)O_(4))+4HNO_(3) to 2Pb(NO_(3))_(2)+2H_(2)O+underset("(B)")(PbO_(2))` `underset("(A)")(Pb_(3)O_(4)+8HCl to 3PbCl_(2)+4H_(2)O+Cl_(2)` `underset("(B)")(PbO_(2))+4HCl overset(Delta)toPbCl_(2)+2H_(2)O+Cl_(2)` |
