Question
(a) Name the halide ion whose oxidation can't be done by chemical method. How it can be oxidised?
(b) Explain the bleaching action of chlorine.
✓

Answer

(a) The oxidation of $F ^{-}$(fluoride ion) can't be done by chemical method because electronegativity of fluorine is maximum the oxidation of fluoride ion is done by electrical decomposition.
(b) In presence of moisture, Cl behave as bleach. From this $ClO ^{-}$and $Cl ^{-}$ion get form. Hypochlorite ion oxidise the colour and make it colourless.
