A) 10 : 1
B) 1 : 12
C) 4 : 1
D) 1 : 5
Correct Answer: C
Solution :
\[\frac{\text{Strength of acid H}{{\text{A}}_{\text{1}}}}{\text{Strength of acid H}{{\text{A}}_{\text{2}}}}\sqrt{\frac{{{K}_{1}}}{{{K}_{2}}}}\] \[\sqrt{\frac{3.0\times {{10}^{-4}}}{1.8\times {{10}^{-5}}}}=\frac{4}{1}\] Hence, the correct option is (c).You need to login to perform this action.
