Webelectrode is a linear function of pH Eglass electrode= E’ – RT/2.303F pH (6) The 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 calculated, it is more practical to calibrate the glass electrode using buffers. WebThe utility of a pC-pH diagram is that all of the ion concentrations can be estimated at the same time for any given pH value. This computer simulation allows the user to select an acid system, enter the pK a values, and draw the pC-pH diagram.
