OxoAcid strength

Postby cristiancampana 2H » Sun Dec 10, 2017 12:41 am

I know that an oxoacid is stronger the more O's it has, but do not know why. Thanks in advance.

The conjugate base is more stable due to resonance and electron withdrawing properties of oxygen.

This is because the negative charge on the conjugate base is stabilized by the electron withdrawing oxygen atoms. The more oxygen atoms there are, the more stable the conjugate base is, and the greater stability of the conjugate base is an indication of the strength of the acid.
