What is khp?

KHP stands for potassium hydrogen phthalate, which is a white, crystalline substance commonly used as a primary standard in volumetric analysis. It has a molecular formula of C8H5KO4 and a molar mass of 204.22 g/mol.

KHP is commonly used in the calibration of pH meters and titrators because it is a stable, high-purity substance that can be accurately weighed and dissolved in water. In acidic solutions, KHP dissociates to release H+ ions which can be used to measure the acidity of the solution.

KHP is also used in the pharmaceutical and food industries as a buffering agent to regulate the pH of products. It has a mild sour taste and is considered safe for consumption in small quantities.

Overall, KHP is an important chemical compound with many practical applications in research, industry, and daily life.
