概要
- 論文の詳細を見る
In non-aqueous titration, the color shade at the equivalence point was decided graphically by utilizing complementary tristimulus colorimetry. It was also shown that the color shade at the equivalence point could be decided from the pK_a value in aqueous solution of a weakly basic sample. Visual detection of the end-point in anhydrious acetic acid was possible when the sample concentration was higher than 10^<-2> M. A general expression for determination of the equivalence point is presented, and factors influencing the titration are discussed.
