If S1, S2, S3 and S4 are the solubilities of AgCl in water, in 0.01 M CaCl2, in 0.01 M NaCl and in 0.05 M AgNO3 respectively at a certain temperature, the correct order of solubilities is

Question

If S1, S2, S3 and S4 are the solubilities of AgCl in water, in 0.01 M CaCl2, in 0.01 M NaCl and in 0.05 M AgNO3 respectively at a certain temperature, the correct order of solubilities is (A) S1 > S2 > S3 > S4 (B) S1 > S3 > S2 > S4 (C) S1 > S2 = S3 > S4 (D) S1 > S3 > S4 > S2

0.01 M CaCl2 â¡ 0.02 M Cl- 0.01 M NaCl â¡ 0.01 M Cl-, 0.05 M AgNO3 â¡ 0.05 M Ag+ [Ag+][Cl-] = Ksp (const.). The concentration of common ion propto (1/solubility)

Q. If $S_{1}, S_{2}, S_{3}$ and $S_{4}$ are the solubilities of $A g Cl$ in water, in $0.01 M C a C l_{2}$ , in $0.01 M N a Cl$ and in $0.05 M A g N O_{3}$ respectively at a certain temperature, the correct order of solubilities is

$S_{1} > S_{2} > S_{3} > S_{4}$

$S_{1} > S_{3} > S_{2} > S_{4}$

$S_{1} > S_{2} = S_{3} > S_{4}$

$S_{1} > S_{3} > S_{4} > S_{2}$

$0.01 M C a C l_{2} \equiv 0.02 M C l^{-}$
$0.01 M N a Cl \equiv 0.01 M C l^{-},$
$0.05 M A g N O_{3} \equiv 0.05 M A g^{+}$
$[A g^{+}] [C l^{-}] = K_{s p}$ (const.).
The concentration of common ion $\propto \frac{1}{so l u bi l i t y}$

Q. If S1​,S2​,S3​ and S4​ are the solubilities of AgCl in water, in 0.01MCaCl2​, in 0.01MNaCl and in 0.05MAgNO3​ respectively at a certain temperature, the correct order of solubilities is

S1​>S2​>S3​>S4​

S1​>S3​>S2​>S4​

S1​>S2​=S3​>S4​

S1​>S3​>S4​>S2​
