We're being asked to determine which of HIO2 and HBrO3 has a larger acid-dissociation constant.
An acid dissociation constant (Ka) is a quantitative measure of the strength of an acid in solution. So the greater the strength of the acid, the larger the acid dissociation constant.
HIO2 and HBrO3 both have H+ ion connected to a nonmetal and oxygen, so they are oxyacids.
Recall that oxyacids can be identified by the fact that they all possess an H+ ion connected to a nonmetal and oxygen, hence the prefix “oxy”.
Which acid has the larger acid-dissociation constant, HIO2 or HBrO3?
