Select the strongest acid from the following list. A)HBrO B)HBrO ₂ C)HClO ₂ D)HClO ₃ E)HIO

Question

Quizplus · Accepted Answer

The strength of an acid is determined by the stability of its conjugate base. The stronger the acid, the weaker its conjugate base. HClO4 is the strongest acid in the group, but it is not listed as an option. However, we can compare the strengths of the remaining acids by examining their conjugate bases. The conjugate base of HClO is ClO-, the conjugate base of HBrO is BrO-, and the conjugate base of HIO is IO-. Among these, the most stable is IO-, making HIO the weakest acid. Similarly, HBrO is stronger than HClO because its conjugate base, BrO-, is more stable than ClO-. Therefore, the strongest acid from the given options is HClO3 or HClO ₃.
