Assertion and Reasoning:
Assertion: During electrolysis of concentrated aqueous solution of sodium chloride, hydrogen is produced at anode and chlorine gas is produced at cathode.
Reasoning: Ions get attracted to oppositely charged electrodes.
Explanation:
During electrolysis, an electric current is passed through an aqueous solution or molten salt. This causes the ions in the solution to move towards the oppositely charged electrodes. The positive ions (cations) move towards the cathode (negative electrode) and the negative ions (anions) move towards the anode (positive electrode).
In the case of concentrated aqueous sodium chloride solution, the cations are Na+ ions and H+ ions (from water) and the anions are Cl- ions and OH- ions (from water). At the cathode, the H+ ions and Na+ ions are attracted towards the negatively charged electrode. However, the H+ ions have a greater tendency to gain electrons and form hydrogen gas (H2) than the Na+ ions. Therefore, hydrogen gas is produced at the cathode instead of sodium metal.
At the anode, the Cl- ions and OH- ions are attracted towards the positively charged electrode. However, the OH- ions have a greater tendency to lose electrons and form oxygen gas (O2) than the Cl- ions. Therefore, chlorine gas (Cl2) is produced at the anode instead of oxygen gas.
Hence, the assertion is true but the reasoning is false. The correct reason for the production of hydrogen gas and chlorine gas during the electrolysis of concentrated aqueous sodium chloride solution is the difference in the tendency of the ions to gain or lose electrons and form gases.
