A scarlet compound (A) is treated with conc. HNO3
to give a chocolate brown precipitate (B) and a
colourless solution of C. On adding KI to this
solution, a yellow ppt. (D) is obtained. The
precipitate (B) on warming with conc. HNO3 in the
presence of Mn(NO3)2 produces a pink coloured
solution due to the formation of (E). What is (E) ?
(A) PbCrO4 (B) PbI2 (C) MnO2 (D) kMnO4
