An electric current of 0.965 ampere is passed for 2000 seconds through a solution containing [Cu(CH3CN)4]+ and metallic copper is deposited at the cathode. The amount of Cu deposited is:
  • a)
    0.005 mol
  • b)
    0.01 mol    
  • c)
    0.02 mol  
  • d)
    0.04 mol
Correct answer is option 'C'. Can you explain this answer?

Equivalent weight of [Cu(CH3CN)4]+ =227/1 =227
mass deposited on cathode = E. W. (I×t) /96500
=227×0.965×2000/96500=4.45 gm
in moles = 4.45/227= 0.01960=0.02 mole
