Abstract
The non-ideality of commercially available glass pH electrode normally used for alkalinity determination by the Gran-type titration has been examined and its effect on the accuracy of the estimated alkalinity evaluated. It is found that slope errors of the glass electrode could be a limiting factor to the accuracy that can be obtained. This error source could be eliminated altogether by applying the proposed 'slope correction' algorithm which uses the titration data for in situ slope calibration of the glass electrode. Application of the proposed method eliminates the need for calibration of the glass electrode and the requirement for thermostating the test solution.
