Question

During the electrolysis of acidified water, two gases A and B are
formed at the two electrodes. The volume of gas A is double than that
of B. Gas A burns with a blue flame with a popping sound. Gas B
supports combustion. Answer the following questions:
a) Name the gases A and B.
b) What type of reaction takes place during electrolysis?
c) What do you conclude from the ratio 2:1 between volumes of A and
B?

Answer 1

Answer:

(a)the gas released at the cathode will be hydrogen and the gas released at the anode will be oxygen

(b) redox

(c)ph will remain same
