Abstract

Potentiometric Titrations.-The potentiometric titrations were performed with a Coleman Electrometer. In each case 0.00063 mole of the compound was dissolved in an excess of 15 ml. of 0.0867 N NaOH and titrated with 0.1140 N HC1. except in the titration of 8- aminoethylnitramine (VI).. 4 solution of 55 X 10-5 mole of this compound was dis5olvrd in 10.2 1111. of 0.1140 N alkali and titrated immediately with 0.1140 HCl. Three inflections ...
