A) \[9:1\]
B) \[3:1\]
C) \[3:2\]
D) \[9:2\]
Correct Answer: B
Solution :
\[\sqrt{\frac{{{K}_{{{a}_{1}}}}}{{{K}_{{{a}_{2}}}}}}=\frac{{{\alpha }_{1}}{{(acid\text{ }strength)}_{1}}}{{{\alpha }_{2}}{{(acid\text{ }strength)}_{2}}}\] \[=\sqrt{\frac{2.7\times {{10}^{-4}}}{3\times {{10}^{-5}}}}=\frac{{{\alpha }_{1}}}{{{\alpha }_{2}}}\] Hence, \[\frac{{{\alpha }_{1}}}{{{\alpha }_{2}}}=\frac{3}{1}=3:1\]
