Galvanic notation
WebJul 20, 2024 · In general, if a galvanic cell is connected to a voltmeter, the electrode connected to the negative terminal of the meter must be the anode. If our shorthand cell notation shows that electrode on the left, then the corresponding cell reaction … The LibreTexts libraries are Powered by NICE CXone Expert and are supported … WebThe notation for voltage in this context is E 0 (“e-naught”). E 0red denotes reduction potential and E 0ox denotes oxidation. E 0cell, or the overall potential for the reaction, is simply the sum of E 0red and E 0ox. Here’s an example putting this all together: Reduction half-reaction: Cl 2 + 2e – → 2Cl –
