... during reaction of alcohols with KI because H2SO4 oxidizes HI to I2. But why this does not happen when H2SO4 react with KBr? Also why H3PO4 not used with KBr? There are two different types of reaction which might go on when concentrated sulphuric acid is added to a solid ionic halide like sodium fluoride, chloride, ... We can work this out by observing the changes in oxidation state of sulphur in concentrated sulphuric acid (H2SO4) when this compound reacts with KCl, KBr ...
