Calculate the number of moles of Copper that will be deposited, if 2 Faraday of electricity is passed through the copper during the electrolysis of copper(II)tetraoxosulphate(VI)

[1F = 96500C ]

0.5 mole

1.0 mole

2.0 moles

3.0 moles

Explanation

NB: 1F = 1 mole of electrons of the atom of an element

In the case of copper (Cu), the valency is 2+.

⇒ Cu\(^{2+}\) + 2e\(^-\) → Cu

So, 2F = 1 mole of Cu

then, 2F = x mole

x = \(\frac{2\times1}{2}\)

x = 1 mole
