CHXI11:THE P-BLOCK ELEMENTS

316262 Assertion :
Oxidising power of perhalates are in the order: \(\mathrm{BrO}_{4}^{-}>\mathrm{IO}_{4}^{-}>\mathrm{ClO}_{4}^{-}\).
Reason :
The standard reduction potential for \(\mathrm{BrO}_{4}^{-}\)is more positive and decreases in the order: \(\mathrm{BrO}_{4}^{-}>\mathrm{IO}_{4}^{-}>\mathrm{ClO}_{4}^{-}\).
