Question
Account for the following observations:
acidity of oxo acid of chlorine is HOCl < HOCIO < HOClO2 < HOClO3
Solution
The acid strength increases:HOCl < HOCIO, < HOCIO2, < HOCIO3.
electronegativity play a role in acid strength.There are conclusions we might draw. A greater electronegativity of the atom or atoms attached to the H-O in the oxyacid apparently results in a weaker H-O bond, which is thus more readily ionized.
Since number of oxygen atom increase thus there acidic chracter is also increases.
