Quimolar solutions of HF, HCOOH and HCN at 298 K have the values of 2HI(g)2HI_{(g)}as 24.824.8and 12\frac{1}{2} respectively. what will be the order of their acidic strength?

A

HF > HCN > HCOOH

B

HF > HCOON > HCN

C

HCN > HF > HCOOH

D

HCOOH > HCN > HF

Answer

HF > HCOON > HCN

Explanation

Solution

: Acidic strength ,∝Ka\propto \sqrt{K_{a}}
