Description
Application
KHP serves as a primary standard for acid-base titrations calibrates pH meters (pH 4.00 buffer) and acts as a reagent in analytical chemistry.
Purpose
Its main purpose is standardization in volumetric analysis due to high purity stability and non-hygroscopic nature ensuring accurate acidity measurements.
General Description
Potassium hydrogen phthalate (CHKO) often called KHP is a white odorless crystalline powder. It is moderately soluble in water (about 80 gL at 20C) has a density of 1.64 gcm and decomposes around 295-300C.
