Begin your capacity testing by using the buret, stir bar, and stir plate described in Part II: Practicing Titrations; Pour the measured 50-mL buffer solution for “ACID” back into the 250-mL beaker ...

Tick ( ) at least two concordant titres. These are titres within 0.20 cm 3 (or sometimes 0.10 cm 3) of each other. Make sure the burette is vertical, and take the readings from the bottom of the ...

The instruments used to determine acid value were a sample changer, titrator with DET mode, buret (20 mL) and a stirrer. A Solvotrode easyClean (6.0229.020) electrode was also employed.

The acid value is also used for evaluating plasticizers, where acid values must be minimized. Instruments and Chemicals. The instruments used to determine acid value were a sample changer, titrator ...
