Question

2. Read the following and answer the questions
In electrolysis, the electric current is used to carry out decomposition. Hence it is an electrolytic decomposition. During the
electrolysis of water, the reaction involved is:
2H20(1) ---> 2H2(g) + O2(9)
a) During electrolysis, the charges carried by anode and cathode are respectively:
a. each +ve
b. each -ve
c. anode : +ve, cathode: -ve
d. anode: -ve, cathode: +ve

Answer 1

Answer:

c.

Explanation:

cathode is negative as it is attached to negative terminal of the battery . at chathode reduction takes place.

anode is positive. as it is attached to positive terminal of the battery. at anode oxidation takes place.
