Problem: Place the species in the following group in order of increasing base strength. Give your reasoning in the case.a. IO3-, BrO3-

FREE Expert Solution

We're being asked to place the given species in the following group in order of increasing base strength

Given:  IO3-, BrO3-

Recall that these are the conjugate bases of the oxyacids HIO3 and HBrO3. We can determine the strength of the conjugate bases using the strength of the acids where they came from,

The stronger the acid, the weaker its conjugate base is.


The strength 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.
