Question

Electrolysis of a aqueous solution of sodium chloride produces
A) hydrogen gas at anode and chorine at cathode
B) Hydrogen gas at cathode and oxygen at anode
C) Hydrogen gas at anode and sodium hydroxide at cathode
D) Chlorine gas at anode and sodium hydroxide at cathode

please give full explanation.

Answer 1

Answer:

Opt b is ur ans

Hydrogen gas at cathode and oxygen at anode

Explanation:becase

Anode is +

Cathode is negative

So unlike charges attract. (I)

so hydrogen at cathode

While oxygenis

Negative soby (I) oxygen at anode

Hope it helps

Mark me brainliest

Answer 2
