Standard redox potential is measured by:

Question

Quizplus · Accepted Answer

DStandard redox potential is measured by using a voltmeter to measure the potential difference (electron flow) between a reference half cell and the sample half cell. A common reference half cell employed is the Standard Hydrogen Electrode (SHE), which involves a solution in equilibrium with H2 gas at 1 atmosphere pressure, not necessarily with the specific concentration and gas mentioned in option D, but the concept of using a reference half cell with a known potential is correct. Options A and B are incorrect because the standard redox potential measurement does not involve detecting proton flow or using a specific salt bridge composition as described.
