A dilute aqueous solution of sodium fluoride is electrolysed ; the products at the anode and cathode are |
|
Answer» lyte: NaF (+H20) aqueous ____________________________Electrolytic REACTION: NaF⇌ (Na+) + (F-) H2O⇌ (H+) + (OH-) _____________________________Reaction at cathode:H+ and Na+ cations come towards the cathode but H+ ions are DEPOSITED.(H+) + e = HH+H= H2 (Hydrogen gas) _____________________________Reaction at anode:OH- and F- ions comes towards the anode but only OH- ions gets deposited at the anode.(OH-) - e= OHOH+OH= H2O + OO+O=O2 (OXYGEN gas) ______________________________Therefore, Products FORMED are:a). Hydrogen:- Cathodeb). Oxygen:- Anode |
