Answer to Question #223456 in General Chemistry for moses

Question

what mass of copper will be liberated during electrolysis by a charge of one faraday?

Answer 1

1/2Cu²⁺(aq)+e^-$\to$ Cu(s)

0.5moles of Cu²⁺(aq)

If 1mole= Cu²⁺(aq) of 63.55g

$\therefore$ 0.5mole=0.5mol*63.55(g/mol)

=31.78g of Cu
