abstract: Maleic, fumaric, tartaric, glutaric and adipic acids are titrated directly with sodium hydroxide by means of an automatic thermometric titrimeter. The titration curves have two break-points, corresponding to the successive neutralization of the two acid groups. Previous standardization permits measurement of the heats of neutralization, from which the enthalpies of dissociation can be deduced. From 0.3 to 1 mmole of acid can be titrated with a relative standard deviation of about 3%.
