Problem: The following acids are listed in order of their increasing acidity. Provide a brief explanation for the observed trends. Note: The Pauling electronegativity values for selected elements are given in Table 1.HIO < HBrO < HClO

FREE Expert Solution

We are asked to provide an explanation for the observed trend where the compounds are arranged in increasing acidity. 

HIO < HBrO < HClO

It can be observed that all of the acids have an O meaning they are oxyacids. 

The strengths of oxyacids is based on the number of oxygens or the electronegativity of the nonmetal in the oxyacid. An oxyacid is considered strong when there are at least 2 or more O than H.

Given:

HIO < HBrO < HClO


The three oxyacids given have an equal number of oxygens. We’ll rank their strength based on the electronegativity of the nonmetal in each oxyacid.
