Acid-base Titration Endpoint Error and MATLAB Programming Construction
The endpoint error of acid-base titration is one of the key and difficult points in the theoretical teaching of analytical chemistry,and the current textbooks are in accordance with different titration systems,derive a large number of formulas for the calculation of error,which is not only complicated,but also mostly approximate.In this paper,we try to derive an end-point error formula that is uniformly expressed in terms of titrant volume,and the corresponding volumes of titrant at the stoichiometric point and titration end-point are numericalized to accurately find the titration end-point error value.Relevant examples show that this method can greatly reduce the difficulty of calculation and effectively reduce the teaching burden.In addition,this paper proposes to use MATLAB to program the algorithm to further enhance the teaching efficiency.
