For this case an acid can be defined as follows:- . National Institutes of Health. ( Note : HI is a strong acid; HF is a weak acid) Solution: (F , Cl, Br, I F is the smallest and I is the largest in size) The radius of I is larger than the radius of F. This is why the H-I bond is weaker than the H-F bond, HI is easier to break than HF, and the Ka for HI is greater.
