Summary
Two different experimental methods for the calibration of glass electrodes for H+ concentration are analysed: strong acid—strong base titration and addition of the strong base or acid to the solvent. Possible systematic errors in acid or base concentrations used for calibration affect in a different way the linear relationship between the cell potential and the logarithm of the hydrogen ion concentration in each case. We have examined how such errors influence the slope of the calibration curve by using a programme that simulates the calibration procedure and we have compared this analysis with some experimental results previously obtained.
