A) \[1.0\times {{10}^{-10}}\]
B) \[1.0\times {{10}^{-8}}\]
C) \[1.0\times {{10}^{-16}}\]
D) \[1.0\times {{10}^{-12}}\]
Correct Answer: D
Solution :
\[AgI\xrightarrow[{}]{{}}A{{g}^{+}}+{{I}^{-}}\] For binary electrolyte \[{{K}_{sp}}={{s}^{2}}\] where s = solubility in mol/L \[1.0\times {{10}^{-16}}={{s}^{2}}\] or \[s=1\times {{10}^{-8}}\,mol/L\] solubility of AgI in KI solution \[=1\times {{10}^{-8}}\,\times {{10}^{-4}}\] \[=1\times {{10}^{-12\,}}mol/L\]You need to login to perform this action.
