Q. A complex is composed of one chromium ion, three bromides and six water molecules. Upon addition of excess AgNO3, 1.0 g aqueous solution of the complex gave 0.94 g of AgBr. The molecular formula of the complex is
(Atomic weight: Cr = 52, Br = 80, Ag = 108, O = 16 and H = 1)
(A) [Cr(H2O)6]Br3
(B) [Cr(H2O)5Br]Br2·H2O
(C) [Cr(H2O)4Br2]Br·2H2O
(D) [Cr(H2O)3Br3]·3H2O
Ans: [Cr(H2O)6Br]Br2.H2O
