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^-.

N a C l left right double arrow N a to the power of plus plus C l to the power of minus

So due to increase in concentration of common ion ( Cl^-) rection will move in backward direction and solubility decreased.

(b)

N a N O subscript 3 left right double arrow N a to the power of plus plus N O subscript 3 to the power of minus

There is no common ion effect so solubility of AgCl will not decreased.

(c)

A g subscript 2 C r O subscript 4 left right double arrow 2 A g to the power of plus plus thin space C r O subscript 4 to the power of minus

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 Ag₂CrO_4, 2 Ag⁺ ions are available for one AgCl molecule. So common ion effect in Ag₂CrO₄ is more effective.
