Why HClO2 is a stronger acid than HBrO2?
HClO2 is a stronger acid than HBrO2. Doesn't the fact that Cl and Br are in the same group and the Br-O bond is longer and weaker than the Cl-O bond outweigh the greater electronegativity of the Cl bond though?

It's the O--H bond that is broken. Also the resulting ClO2- is more stable due to Cl's higher electronegativity.

Is this true every time there's an O2 in an acid? The hydrogen will be bound to one oxygen?

Since there is an equal amount of oxygens, you look at which is more electronegative (Br or Cl) and since Cl is more electronegative, it is the stronger acid.

Re: Why HClO2 is a stronger acid than HBrO2?
HBrO2 I believe is actually stronger because the O will pull the Br away from the H more so then the O will pull the Cl away from the H. Always the more electro neg atom is the strongest acid.

Does this apply to HNO3 and HNO2 as well? I said HNO3 is stronger because the extra oygen in the molecule helps stabilize the charge from the lone pair.

I honestly thought this was related to the electronegativity of the element. Thanks for all the help.
