A lead compound (X) on strong heating gives a brown gas (B), a colourless gas (C) and a yellow residue (D); (D) on further heating in air at about 470 °C gives a bright red compound (E). Which of the following statement(s) is/are CORRECT?
Options:(select one or more)
Answer:
A, B, C
Solution:
2Pb(NO₃)₂ → 2PbO + 4NO₂↑ + O₂↑, so B = NO₂, C = O₂ (not N₂) and D = PbO; 6PbO + O₂ 2Pb₃O₄, so E = Pb₃O₄, a mixed Pb(II)/Pb(IV) oxide.
