A dilute aqueous solution of sodium fluoride is electrolyzed, the products at the and cathode are

Options

A. `O_(2)` and `K `
B. `O_(2)` and `F_(2)`
C. `H_(2)` and `F_(2)`
D. `O_(2)` and `H_(2)`

Answer

D

Explanation

Since reduction potential of `H_(2)Ogt` reduction potential of `K^(o+)` ions. So the reduction of water occurs to give `H_(2)(g)` at cathode.
At cathode `:`
Similarly, oxidation potential of `H_(2)Ogt` oxidation potential of `F^(c-)` ions. So again the reduction of water occurs to give `O_(2)(g)` at anode.
At anode `:`
