Question

a dilute aqueous solution of sodium fluoride is electrolysed the product at the anode and cathode are

Answer 1

When electricity is passed through NaF ,

NaF --------> Na+ + F-

The sodium cation (positive) gets attracted to the cathode (negative) and the fluorine anion (negative) is attracted towards the anode (positive).

Thus Na is produced at cathode and fluorine is liberated in the anode.

Answer 2

Ans :O₂ , H₂

electrolysis of NaF , then there is no change in NaF . it uses only for producing current and breaking water and form H2 and O2 gas .

hence, A dilute aqueous solution of sodium fluoride ( NaF ) is electrolysed , the produce at anode : oxygen gas and produce at cathode : Hydrogen gas
