The dissociation constants of formic and acetic acids are 1.77 × 10−4 and 1.75 × 10−5, respectively.

Question

The dissociation constants of formic and acetic acids are 1.77 × 10−4 and 1.75 × 10−5, respectively. Which of the following statement is correct?

Accepted Answer

$\frac{\left\lbrack H^{+} ightbrack_{HCOOH}}{\left\lbrack H^{+} ightbrack_{CH_{3}COOH}} = \frac{\left( \sqrt{K_{a}.C} ight)_{HCOOH}}{\left( \sqrt{K_{a}.C} ight)_{CH_{3}COOH}} = \sqrt{\frac{1.77 	imes 10^{- 4}}{1.75 	imes 10^{- 5}}} = 3.18$
