Let the solubilities of `AgCI` in `H_(2)O`, and in `0.01M CaCI_(2), 0.01M NaCI`, and `0.05M AgNO_(3)` be `S_(1),S_(2),S_(3),S_(4)`, respectively. What is the correct relationship between these quantites.

A

`S_0 gt S_1 gt S_2 gt S_3`

B

`S_0 gt S_2 gt S_1 gt S_3`

C

`S_0 gt S_1 = S_2 gt S_3`

D

`S_0 gt S_1 gt S_3 gt S_1`

Text Solution

Verified by Experts

The correct Answer is:
B
`"Solubility "= ("Solubility Product")/(Concentration of common ion")`
`S_(1)=(K_(sp))/(0.02)=50K_(SP)`
`S_(2)=(K_(SP))/(0.01)=100 K_(SP)`
`S_(3)=(K_(SP))/(0.05)=20 K_(SP)`
So, `S_(2) gt S_(1) gt S_(3)` Again solubility will be greatest in water.
So, `S_(0) gt S_(2) gt S_(1) gt S_(3)`
