b. electrolyte
c. cathode
d. none of these

5 In electrolysis of water, which gas is produced at the anode?
a .hydrogen
b. oxygen
c. carbon dioxide
d .nitrogen HYDROGEN

​

Answer 1

1) a) ZnO

=> Zn(heated) + H2O(steam)----------> ZnO + H2

2) a)anode

=> The positive electrode is the anode, anions migrate to the anode and are oxidized to give neutral atoms.

3) b) Oxygen

=> The anode is positively charged, so the anions or negative ions migrate towards it, in this case Hydroxyl ions (OH-1) .

At Anode:

=> 4OH-1 ---------> 4OH + 4e-

=> 4OH----------> 2H2O + O2 (Oxygen gas)
