Comparing Strengths of Acids and Bases

CHEM-DMW54Z

The equilibrium constant for the following reaction is $2.3\space \times \space { 10 }^{ 3 }.\space$

$$HX(aq)\space +\space { Y }^{ - }(aq)\space \leftrightarrow \space X^{ - }(aq)\space +\space { H }Y(aq)\space $$

Based on this we can conclude

A

$HX$ is a stronger acid than $HY$.

B

$HX$ is a weaker acid than $HY$.

C

$HX$ is a strong acid and $HY$ is a weak acid.

D

$HY$ is a strong acid and $HX$ is a strong acid.
