The acidic strength of HF, HCl, HBr, and HI varies in order :HI> HBr> HCl> HF.It increases down the group.Acidic strength depends on the bond strength between hydrogen and halides as the size increases going down the group liberation of H+ ions becomes easier due to increased size and weak bond strength.
