Q. In dilute aqueous solution HF is a weaker acid than HI because

The p-Block Elements - Part2

Solution:

HI is strongest acid because due to largest size of I, the H-I bond is weakest and its bond dissociation energy is least so it breaks most readily and hence HI is the strongest acid. The order of acidic strength is
HI > HBr > HCl > HF
