Answer to Question #77407 in Electricity and Magnetism for Ajay Krishnan

Question

In an experiment, 295 mg of copper is deposited when a current of 500 mA passes for 30 minutes. Find the electrochemical equivalent of copper?

Answer 1

The Faraday’s law of electrolysis states
m=kIt
So, the electrochemical equivalent
k=m/It=(295×〖10〗^(-6) kg)/(500×〖10〗^(-3) A×30×60 s)=328.8×〖10〗^(-9) kg/s
