Question

Solubility of AgCl in water , 0.01 M CaCl₂, 0.01 M NaCl and 0.05 M AgNO3 are S1, S2, S3andS4 respectively then.

• A. S1> S2> S3> S4
• B. S1 > S3> S2> S4
• C. S1> S2 = S3> S4
• D. S1 > S3>S4< S2

Answer 1

Answer: (B)

S1 > S3> S2> S4

Answer 2

$\mathrm { AgCl } \quad \mathrm { Ag } + \mathrm { Cl } ^ { - }$

In $\mathrm { CaCl } _ { 2 }$

$\mathrm { CaCl } _ { 2 } \quad \mathrm { Ca } ^ { + 2 } + 2 \mathrm { Cl } ^ { - }$

Common ion effect is maximum in AgNO3

So, $S _ { 1 } > S _ { 3 } > S _ { 2 } > S _ { 4 }$
