Statement 1 : Amongst the oxo acids of halogens, HOCl, HOBr and HOI, the HOI is the most acidic acid.

Statement 2 : The conjugate base stability is ${\mathrm{CIO}}^{-}>{\mathrm{BrO}}^{-}>{\mathrm{IO}}^{-}.$

Order of acidic character is $\mathrm{HClO} >\mathrm{HBrO} >\mathrm{HIO}$ as the order of the stability of their conjugate base is ${\mathrm{CIO}}^{-}>{\mathrm{BrO}}^{-}>{\mathrm{IO}}^{-};$ because Cl being small size atom can form effective $\mathrm{\pi }-$bond with oxygen.
