Calculate the equivalent weight and electrochemical equivalent of copper deposited from cupric salt (At. Wt of `Cu = 63.5)`.

Explanation

Deposition of Cu from cupric salt electrolytically is given as,
`Cu^(2+)+2e^(-) rarr Cu`
Equivalent weight of copper `= ("Atomic weight")/("Valency") = (63.5)/(2) = 31.75`
Electrochemical equivalent of copper `= ("Equivalent weight")/(96,500)=(31.75)/(96,500)=3.29xx10^(-4)"g coul"^(-1)`.
