So this is the same current for all three cells. Now we can write our half reaction for copper, which will be see you two plus plus two e minus forms. See you solid. And so now we can take our one point seven four grams, …


electrolysis, process by which electric current is passed through a substance to effect a chemical change.

The process of splitting water (H 2 O) into its atomic components (hydrogen and oxygen) using electricity is known as electrolysis. This experiment has significant implications in terms of what these 2 gases can be used for in their own right, with hydrogen being one of the cleanest sources of energy we have access to.


A process for purifying and refining gold to 98+% purity is dislosed. The gold to be refined is made the anode in an electrolytic cell with a solution of ammonium chloride as the electrolyte. The purified gold is collected in anode bags and the non-gold impurities including silver are dissolved in the electrolyte. The silver is complexed with the ammonium ion in the electrolyte.


Electrolytic cells can be used to produce oxygen gas and hydrogen gas from water by subjecting it to electrolysis. These devices can also be used to obtain chlorine gas and metallic sodium from aqueous solutions of sodium chloride (common salt). Another important application of electrolytic cells is in electroplating.


I have a client who has a cell which has been producing for a year now but he spaced the basket (it's a Thum cell) too far from the cathode (6") and when I was in to see him, coincidentally on a day when he had the cell broken down to change the electrolyte, I pointed out the problem. He has...
