A) \[1\times {{10}^{-4}}\]
B) \[1\times {{10}^{-2}}\]
C) \[1\times {{10}^{-3}}\]
D) \[1\times {{10}^{-3}}\]
Correct Answer: B
Solution :
\[pKa=5\], so \[Ka=1\times {{10}^{-5}}\] \[\alpha =\sqrt{\frac{Ka}{C}}=\sqrt{\frac{1\times {{10}^{-5}}}{0.1}}=1\times {{10}^{-2}}\]You need to login to perform this action.
