Leírás

Általános leírás

Potassium hydrogen phthalate, also known as KHP, is a volumetric standard produced under stringent conditions and measured with the highest possible precision. The content of the standard is measured using volumetric acid-base titrations. Its certified value and uncertainty measurement are in accordance with ISO Guide 35.

Alkalmazás

It finds its use as a reference material for the standardization of volumetric solutions in alkalimetric titrations.
