A) \[4.77\times {{10}^{-5}}\]
B) \[9.77\times {{10}^{-5}}\]
C) \[4.99\times {{10}^{-10}}\]
D) \[5.64\times {{10}^{-10}}\]
Correct Answer: D
Solution :
\[{{K}_{a}}=\frac{{{K}_{w}}}{{{K}_{b}}}=\frac{{{10}^{-14}}}{1.77\times {{10}^{-5}}}=5.64\times {{10}^{-10}}\]You need to login to perform this action.
