A) \[1.0\times {{10}^{-4}}\]
B) \[1.0\times {{10}^{-5}}\]
C) \[1.0\times {{10}^{-3}}\]
D) \[1.0\times {{10}^{-8}}\]
Correct Answer: B
Solution :
\[pH=3\], \[[{{H}^{+}}]={{10}^{-3}}M\] \[\because [{{H}^{+}}]=\sqrt{K\times c}\] \[{{[{{10}^{-3}}]}^{2}}=K\times c\] ; \[\frac{[{{10}^{-6}}]}{0.1}=K={{10}^{-5}}\]You need to login to perform this action.
