Potassium hydrogen phthalate Chemical Properties,Uses,Production

Chemical Properties

white crystalline powder

Uses

As primary standard for preparing volumetric alkali solutions, also as a buffer in pH determinations.

Purification Methods

Crystallise it first from a dilute aqueous solution of K2CO3, then H2O (3mL/g) between 100o and 0o. Before being used as a standard in volumetric analysis, analytical grade potassium hydrogen phthalate should be dried at 120o for 2hours, then allowed to cool in a desiccator. [Beilstein 9 IV 3169.]
