A) \[{{10}^{-5}}\]
B) \[{{10}^{-4}}\]
C) \[{{10}^{-3}}\]
D) \[{{10}^{-2}}\]
Correct Answer: C
Solution :
Degree of dissociation \[(\alpha )=10%=\frac{10}{100}=0.1\] C (concentration)\[=0.1\text{ }M\] \[{{K}_{a}}={{\alpha }^{2}}C\] \[={{(0.1)}^{2}}\times 0.1\] \[={{10}^{-3}}\]You need to login to perform this action.
