All electrode potentials are measured with respect to which reference electrode?1 pointCalomel electrodeHydrogen absorbed on platinum electrodeGold electrodeHydrogen electrod

Electrode Potential:

The electrode potential of normal hydrogen electrode is

n which circuit does the voltmeter read the potential difference across the lamp?*2 points

The potential of an electrochemical reaction depends on the concentration of reduced and oxidised species.The change from the standard potential can be calculated with the Nernst equation.For a glass electrode, this results in:E = Ecell - 0.059 x pH VoltsYou find that the potential of a solution with unknown pH is 0.177 V higher than the potential of the calibration buffer at pH 7.What is the pH of the solution? 2 10 4 8 6
