At 58:26, If you multiply the reaction by 2, wouldn't the half reaction then be 1.54V? And the new total would be 1.77V? edit: 1:03:12 The answer is no.

@favourfriday7153 5 ай бұрын

If the reaction is multiplied by a coefficient the cell potential won't be affected or altered. It is only altered when the reaction is reversed.

How was it

@romandarko2415 3 жыл бұрын

whilst most of the content was fairly clear, i was a little mystified at the end where predictions were made as to reaction products at anode and cathode. In my hands on experience, if using HCL as the electrolyte/solvent, you normally see Cl2 being generated at the anode and a codeposition of H2 gas and copper on the cathode. If using H2SO4 as electrolyte, water will be oxidised to O2 at the anode and you still see H2 gas and Cu deposition at the cathode.

Mistake at 32:52, this is not a product-favoured system, Q is the initial concentration ratio. However, the positive standard cell potential is indicating that it is a product-favoured system since the reaction is spontaneous. Am I correct?

In the battery that consist of Ni and Fe, Why Ni is the Anode? Since Ni is lossing electrons, it should be cathode

@TheOrganicChemistryTutor 7 жыл бұрын

In a galvanic cell, the anode is the one that always loses electrons. Oxidation always occur at the anode. The electrons flow from the anode to the cathode. I hope that answers your question :)
