Question

STATEMENT-1 : Electrolysis of acidulated water using inert electrodes results in evolution of gases at cathode and anode both. 

STATEMENT-2 : Al³⁺ discharges more readily than Zn²⁺ at cathode. 

STATEMENT-3 : In an electrolytic cell, cations move towards anode. 

(1) F T T 

(2) T T T 

(3) F T F 

(4) T F F 

Answer 1

Correct option (4) T F F  

Explanation:

In electrolysis of acidulated water, H₂ and O₂ is evolved in 2 : 1 volume ratio, at cathode and anode respectively

discharges more readily at cathode. 

In an electrolytic cell, cations move towards cathode, i.e., negative electrode.
