Webb13 nov. 2024 · The Nernst equation for this cell is. E = E ° − (0.059 n)log10Q = 0 − 0.29log100.1 = + 0.285V. Note that E ° for a concentration cell is always zero, since this would be the potential of a cell in which the electroactive species are at unit activity in both compartments. E ° for a concentration cell is always zero, WebbThe Eglass electrodeis measured with a pH meter, a voltmeter with circuitry allowing direct readout of pH. The meter sub-tracts the potential offset E’. Although it could be …

At low pH, typically < 1, glass membranes are susceptible to saturation by H +, and produce pH readings that are higher than actual. Specialty glasses are available that minimize these errors if routine ... au pontaポイント 支払い
