A) \[1.8\times {{10}^{-5}}\]
B) \[1.8\times {{10}^{-10}}\]
C) \[5.55\times {{10}^{-5}}\]
D) \[5.55\times {{10}^{-10}}\]
Correct Answer: D
Solution :
We know\[{{K}_{H}}=\frac{{{K}_{w}}}{{{K}_{b}}}\] Here\[{{K}_{H}}=?\] \[{{K}_{w}}={{10}^{-14}},\,\,{{K}_{b}}=1.8\times {{10}^{-5}}\] \[{{K}_{H}}=\frac{{{10}^{-14}}}{1.8\times {{10}^{-5}}}=0.555\times {{10}^{-9}}\] \[=5.55\times {{10}^{-10}}\]You need to login to perform this action.
