Expert Answer
Solubility is reduced due to common ion effect.
When AgCl is dissolved it releases Ag+ and Cl- ions
(a) NaCl -NaCl will release Na+ and Cl- .
So due to increase in concentration of common ion ( Cl-) rection will move in backward direction and solubility decreased.
(b)
There is no common ion effect so solubility of AgCl will not decreased.
(c)
Here common ion effect is due to Ag+ ions. So solubility is decreased.
This decrease in solubility will be more as compared to NaCl because in NaCl, 1 Cl- ion is available for one AgCl molecule, In Ag2CrO4, 2 Ag+ ions are available for one AgCl molecule. So common ion effect in Ag2CrO4 is more effective.
Order of solubility -
b>a>c
