B. electrons travel from the cathode to the … WebZn is below Cu on the Standard Reduction Table so Zn will undergo oxidation making it the anode. This means Zn2+ ions will be created. This creates too much positive charge so these ions will migrate towards the salt bridge. ... The anode is where oxidation takes place. Metals will be converted into cations so the electrode will lose mass.

WebOct 6, 2024 · In aqueous solution the anode will oxidize the water instead, as this reaction can be done at much lower potential than oxidizing the sulfate ion. Sulfates can be … WebIf we add the standard reduction potential and the standard oxidation potential together we should get the standard potential for the cell. So let's go ahead and do that. The standard cell potential is equal to, this would be positive .8 volts. So positive .8 volts plus positive .76 volts. Plus positive .76 volts.
