Preparing a standard solution of potassium hydrogen phthalate C0153

High School Chemistry
Excess solutions of potassium hydrogen phthalate could be disposed of down the foul water drain, but it is probably better to have them taken away by a professional chemical waste disposal company.
The second experiment from the classic ILPAC chemistry course from the 1980s Preparing a standard solution of potassium hydrogen phthalate.
4.81g of solid potassium hydrogen phthalate was dissolved in water and made up to 250ml in a volumetric flask.
The concentration of the potassium hydrogen phthalate can be calculated.
A homage to Alec Thompson and the ILPAC course.
Bioaccumulation of phthalates in general, is a problem in the environment and it is now recommended that alternatives are used in school titration experiments.
