Oxidizing power of halogens: A halogen of lower atomic number will oxidize
halide ion of higher atomic number and therefore will liberate
from their salt solution.
(b) As the size of halogen increases the inter nuclear
forces decreases, thus the acidity increases.
(c) This can be explained on the basis of Lowry
Bronsted concept. According to this concept, a strong acid has a weak conjugate
base and weak acid has a strong conjugate base. The conjugate basis of the
oxyacids of chlorine is shown below:
Let us consider the stabilities of the conjugate bases, formed from
