A) \[5\times {{10}^{-5}}\]
B) \[5\times {{10}^{-4}}\]
C) \[5\times {{10}^{-3}}\]
D) \[5\times {{10}^{-7}}\]
Correct Answer: B
Solution :
Key Idea: Degree of hydrolysis\[(h)=\sqrt{\frac{{{K}_{h}}}{C}}\] where\[{{K}_{h}}=\]hydrolysis constant\[2.5\times {{10}^{-9}}\] \[C=\]concentration\[=0.01\,\,M\] \[\therefore \] \[h=\sqrt{\frac{2.5\times {{10}^{-9}}}{0.01}}\] \[=5\times {{10}^{-4}}\]You need to login to perform this action.
