A) \[1.68\times {{10}^{-12}}\]
B) \[1.55\times {{10}^{-10}}\]
C) \[12.4\times {{10}^{-8}}\]
D) \[1.73\times {{10}^{-14}}\]
Correct Answer: B
Solution :
| [b] Solubility of \[AgCl\] in water |
| \[=1.79\times {{10}^{-3}}g/L\] |
| \[=\frac{1.79\times {{10}^{-3}}}{143.5}mol/L\] |
| \[=1.247\times {{10}^{-5}}mol/L\] |
| For \[AgCl\] |
| \[{{K}_{sp}}=S\times S={{S}^{2}}\] |
| \[={{(1.247\times {{10}^{-5}})}^{2}}\] |
| \[=1.55\times {{10}^{-10}}mo{{l}^{2}}{{L}^{-2}}\] |
