Question

Which of the following aqueous solution will result in maximum number of moles of metal deposited on passing same charge?

Answer 1

Answer:3 Faradays of electricity will deposit 3 Equivalents of any metal at the cathode Equivalent Mass of Ag+= 108

Equivalent Mass of Cu2+=63.54/2=31.77

Equivalent Mass of Au3+=197/3=65.67

The Molar ratio of Ag:Cu:Au

=1 : 1/2 : 1/3

=6 : 3 :2
