Precise manual enthalpimetric titrations

A procedure for high precision enthalpimetric titrimetry is described, in which titrant is added in small increments at regular intervals in the equivalence-point region of the titration, with temperature measurements being made after each addition. Many of the inaccuracies associated with the widely used continuous titration procedure are eliminated and relative standard deviations of as low as 0·1 per cent. can be achieved.
