plezzzz ☺☺..
anyone give me ans.

TheEdward:
at cathode ---->H2 and at anode------> O2
pakaa right hi
ok tqu ☺
yes dear
ok tqu
Reduction at cathode: 2 H+(aq) + 2e− → H2(g)
Oxidation at anode: 2 H2O(l) → O2(g) + 4 H+(aq) + 4e−
The gas at anode is Hydrogen
The gas at cathode is oxygen
The volume of hydrogen at anode is double that of oxygen at cathode because water is composed of hydrogen and oxygen in the ratio 2:1
The evolved gases can be tested by burning candle
The candle when brought near hydrogen burns with a pop sound and while brought near oxygen supports burning
Hope it helps:)

HEY , HERE'S THE ANSWER ⏬
i) The gas collected at the cathode is Hydrogen and the collected at the anode is Oxygen.
ii) 2H2O --------> 2H2 + O2
Therefore , the volume of hydrogen is double than the volume of oxygen . This is because the hydrogen has 2 moles in it as compared to the oxygen.
iii) The evolved gas is Oxygen . We can test the evolution of oxygen by the help if tracing the pop sound produced by oxygen.
HOPE IT HELPS YOU ✌️!!!
