Electrolysis of a solution containing an unknown metal ion with a +3 charge deposited 0.159 g of the metal on the cathode over a period of 2.00 minutes at a constant current of 2.00 A. What is the molecular weight of the unknown?
mass of metal liberated, m = (I*t*M)/ (F*z)
I = current (A), t = ...
This solution helps with a problem regarding electrolysis of a solution.
