Halogen Acids | MCQs

Explanation

Among the halogen acids (HF, HCl, HBr, and HI), HI (hydroiodic acid) is the strongest.

The strength of an acid is determined by the ease with which it can donate a hydrogen ion (H+).

The H-I bond is the weakest of the halogen acid bonds, allowing HI to readily dissociate in water and release H+ ions.
