Question

1) Name the two gases formed when electric current is passed through water containing few drops of acid

Answer 1

Answer: Hydrogen and Oxygen

Explanation: Water being a polar covalent compound with a few drops of sulphuric acid which is also a polar covalent compound gets dissociated to form $H^+ ,OH^-$ ions which on the passage of electricity get reduced in the cathode and oxidised at the anode respectively to form Hydrogen gas and Oxygen gas.

Equations:

(i)At cathode: $2H^+ +2 e^- ----> H2$

(ii)At Anode: $4OH^- -4e^- ---->2H2O + O2$

Answer 2

Answer:

Hydrogen and Oxygen.
