Question:
What is the change in mass (in grams) of the cathode if a (1.2150 x {eq}10^1 {/eq}) A current runs for (8.55 x {eq}10^0 {/eq}) h during the electrolysis of a solution of nickel(II) bromide?
(Answer to 3 significant digits)
(Note: Your answer is assumed to be reduced to the highest power possible.)
Electrolysis:
Electrolysis is a process by which a direct electric current is used in order to stimulate a supposedly non-spontaneous chemical reaction. This type of technique is carried out in an electrolytic cell, where there should be an oxidation-reduction reaction that is contained in positive and negative electrodes separated and immersed in a solution composed of negatively and positively charged ions.
