Potassium Hydrogen Phthalate
Full Form of KHP
What is KHP?
Potassium Hydrogen Phthalate (KHP) is a white crystalline powder used extensively as a primary standard in acid-base titrations and pH calibration. In the Indian educational system, KHP is a staple in high school and college chemistry laboratories, particularly for standardizing sodium hydroxide solutions. Its high purity, stability, and precise molar mass (204.23 g/mol) make it ideal for accurate volumetric analysis. KHP is also utilized in environmental testing and pharmaceutical quality control across Indian industries. Students encounter KHP frequently in practical exams for NEET, JEE, and various state board examinations, where titration setups involving KHP are common. The compound is non-hygroscopic and can be dried easily, ensuring consistent results. Its role in teaching fundamental concepts of stoichiometry and equivalence points is invaluable. In research laboratories, KHP serves as a reference material for acid-base equilibria. Overall, KHP remains a cornerstone of analytical chemistry in India, bridging theoretical knowledge with hands-on skill development.
