Fluorine reacts with ice and results in ...

Fluorine reacts with ice and results in the change.
`H_(2)O(s)+F_(2)(g)toHF(g)+HOF(g)`
Justify that this reaction is a redox reaction.

Text Solution

Verified by Experts

The electron density at O - atom decreases when the O - H bond changes to O - F since electronegativity of F is more than H. The decrease in electron density is reduction.
The electron density in `F_(2)` is zero, but in HOF the electron density in F increases. The increase in electron density is reduction.
So the above reaction is redox reaction.
