Oxoacids Trends

Why does the strength of the acid increase for an oxoacid when the oxidation number of the central atom increases?

Increasing the number of oxygens increases the strength of the acidity because the additional O helps to pull out the atom easily. For example in HClO2 and HClO, the extra oxygen of HClO2 makes it stronger and easier to pull out the H atom from the H-O bond. Also, the oxidation state of the Cl is greater in HClO2.
The important fact to know is that acids with more oxygens are stronger and the strength of the acid increases with more oxygens.
