In electrolysis of dil. 
using platinum electrodes:
A
is evolved at cathode
B
is produced at anode
C
is obtained at cathode
D
is produced at cathode
Text Solution
Verified by ExpertsThe correct answer is:
A
Dilute sulphuric acid contains 
and 
ions. At cathode;
ion undergoes reduction by taking up electrons to form 
At anode;
For maintaining a reaction, sulphate ions are not oxidised but remain in the solution at the end. The concentration of 
ions is too low. Thus, 
ions are discharged in preference over 
giving off 
gas.
