When equal volumes of the following solutions are mixed, precipitation of AgCl `(K_(sp) =1.8 ×10^(-10)`) will occur only with:

A

`1 0 ^(-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:
A
Q for AgCl `= [Ag ^(+) ] [Cl ^(-)] = [ (10 ^(-4) xx V )/( 2 V) ] [(10 ^(-4) xx V )/( 2 V )] 2. 5 xx 10 ^(-9) because Q gt K _(sp),` precipitation will occur.
