A Improvement of the Student's Experiments in Physical Chemistry(Ⅴ)-A Simulation of the Titration Curbes in the Reaction of a Monoamino Monocarboxylic Acid with a Monoacidic Base(Ⅱ)-

前報［1］と同様の方法に因って導いた二つの厳密式を用いて，モノアミノ・モノカルボン酸の滴定曲線を計算した。両式の計算結果の差は，等電点までは非常に小さく十分無視できるが，それ以後の過程では急速に増し，当量点以後には約0．3％にも達した。この他，添加酸の物質量と解離指数，滴定液の解離指数および滴定反応中に生じる電荷を有する塩の解離指数などを変化させて滴定曲線に与える影響を調べた。The titration curves of a monoamino-monocarboxylic acid were calculated with the two exact equations,which were derived on the basis of the previous method 1).The difference between the calculated results from these equations were so very small as to be negligible until the isoelectic points,but rapidly increased beyond that point,and the value even reached about 0.3% after the equivelent point.In addition,we investigated the effects of the variation in the some factors on the titration curves.The factors were the amount of the materials and the dissociation constants of the annexing acid,the dissociation consant of the titrant,and the dissociation constants of the two salts with net charge produced in the titration,etc
