Solution
The correct option is BS0>S2>S1>S3 The solubility of AgCl or its ion formation will depend inversely on the concentration
S0=H2O
S1=0.01MCaCl2
S2=0.01MNaCl
S3=0.05MAgNO3
H2O is dilute solution and least concentrated hence have maximum solubility of AgCl in it. Out of NaCl and CaCl2, the solubility of NaCl is high due to loess number of ions produced from NaCl
as compare to CaCl2. More the ion produced lesser is the solubility of coming salt.
So, the Correct order is S0>S2>S1>S3
We know that concentration of common ion α1solubility. The order of solubility of AgCl:S1>S3>S2>S4
