Metal nitrate (A) on heating decomposes, leaving a solid residue (B) which goes into solution with dilute HCI. The solution of (B) gives a white precipitate with ammonium carbonate solution. The precipitate (C) is dissolved in dilute HCI and the solution is treated with potassium chromate to get yellow precipitate (D). The solution (B) with dilute H_(2)SO_(4) also gives a white precipitate (E) insoluble in dilute HCl and nitric acid. The precipitate (E) is a part of a white pigment lithopone.QThe compound (E) is:
