Which of the following statements is correct for a solution saturated with `AgCl` and `AgBr` if their solubilities in moles per litre in separate solutions are `x` and `y` respectively?

Options

A. `[Ag^(+)]=x+y`
B. `[Ag^(+)]=[Br^(-)]+[Cl^(-)]`
C. `[Br^(-)]=y`
D. `[Cl^(-)]`

Answer

B

Explanation

`AgClhArrunderset((x+y))underset(x)(Ag^(+))+underset(x)underset(x)CI^(-)` `AgBrhArrunderset(x+y)underset(y)(Ag^(+))+underset(y)underset(y)BR^(-)`
So `[Ag^(+)]=[Br^(-)]+[CI^(-)]`
