Question

In the complex with formula `MCl_(3).4H_(2)O` the co-ordination number of the metal M is six. And there is a no molecule of hydration in it. The volume of 0.1 M `AgNO_(3)` solution needed to precitate the free chloride ions in 200 ml of 0.01 M solution of the complex is
A. 40 ml
B. 20 ml
C. 60 ml
D. 80 ml

Answer 1

Correct Answer - 2
Formula of complex is `[MCl(H_(2)O)_(4)]Cl`. Ionisable `Cl^(-)` atoms are only one. `M_(1)V_(1) =M_(2)V_(2), Vxx0.1 = 200X0.1`
