Following reactions may occur at cathode during the electrolysis of aq

1.	Following reactions may occur at cathode during the electrolysis of aqueous CuCl2 solution using Pt electrodes:Cu2+(aq) + 2 e- → Cu(s) :E° = +0.34 VH+(aq) + e- → 1/2H2(g) : E° = 0.00 VOn the basis of their standard electrode potential values, which reaction is feasible at cathode and why ?
Answer» Cu²⁺(aq) + 2 e^- → Cu(s) Becaus.e it has higher reduction potential. Detailed Answer: As reaction with higher value of standard electrode potential occurs at cathode get reduced. So, the reaction occurring at cathode is Cu²⁺(aq) + 2 e^- → Cu(s)

Answer»

Cu²⁺(aq) + 2 e^- → Cu(s)

Becaus.e it has higher reduction potential.

Detailed Answer:

As reaction with higher value of standard electrode potential occurs at cathode get reduced. So, the reaction occurring at cathode is

Cu²⁺(aq) + 2 e^- → Cu(s)
