| Abstract: | Based on the general equation of acid-base titration,the least square method is used for calculating the concentrations of mixed acids.The method is simple and suit- able for determining different kinds of samples.The titration is performed potentiometri- tally,several examples are given and the analytical results are with an average relative error of 2%. |
