When equal volumes of the following solutions are mixed, precipitation of `AgCI (K_(sp) = 1.8 xx 10^(-10))` will occur only wity

A

`10^(-4) M [Ag^(+)] " and "10^(-4)M[Cl^(-)]`

B

`10^(-5) M [Ag^(+)]" and "10^(-5)M[Cl^(-)]`

C

`10^(-6)M[Ag^(+)]" and " 10^(6)M [Cl^(-)]`

D

`10^(-10)M[Ag^(+)] " and " 10^(-10)M[Cl^(-)]`

Text Solution

Verified by Experts

The correct Answer is:
1
We look for the case where the ionic product exceeds the `K_("sp")`.
(1) `[Ag^(+)][Cl^(-)] = (1/2 xx 10^9-4)^(2) = 2.5 xx 10^(-9) ` [As the dilution factor for `Ag^(+)" and "Cl^(-) ` is 2 ]
