Write the reaction of F_(2) and Cl_(2) with water.

Answer»

Solution :`F_(2)` being a strong oxidising agent oxidises `H_(2)O` to `O_(2)` or `O_(3)`.
`{:(2F_(2)(G) + 2H_(2)O(l) rarr 4H^(+)(aq)+4F^(-)(aq)+O_(2)(g)),(3F_(2)(g)+3H_(2)O(l) rarr 6H^(+)(aq)+6F^(-)(aq)+O_(3)(g)):}`
`Cl_(2)`, on the other hand, reacts with `H_(2)O` to form hydrochloric acid and hypochlorous acid
`Cl_(2)(g)+H_(2)(l) rarr underset("Hydrochloric acid")(HCl (aq))+underset("Hypochlorous acid")(HOCl (aq))`
