Product Overview
Potassium hydrogen phthalate (KHP) is a highly stable, non-hygroscopic crystalline powder widely recognized for its precision in analytical chemistry. This ARS and ACS-grade reagent ensures exceptional purity, making it ideal for critical applications such as pH calibration and acid-base titrations. Its molecular formula (C₈H₅KO₄) guarantees consistent performance, minimizing errors in quantitative analyses. The compound’s low solubility in water allows for controlled dissolution, while its resistance to atmospheric moisture ensures long-term stability during storage. Whether used as a primary standard or in volumetric analysis, this KHP variant adheres to stringent quality benchmarks, offering reproducibility and reliability. The absence of impurities and its well-defined stoichiometry further enhance its suitability for high-accuracy laboratory procedures. Compatible with most standard lab equipment, it integrates seamlessly into existing workflows without requiring additional adjustments.
FAQs
1. What is the shelf life of Potassium Hydrogen Phthalate ARS, ACS grade?
When stored in a cool, dry place in its original sealed container, this product retains its stability and purity for up to 3 years from the date of manufacture.
2. Can this KHP be used for preparing standard solutions in non-aqueous solvents?
While primarily designed for aqueous solutions, it can be dissolved in certain polar organic solvents like ethanol, though solubility may vary and should be pre-tested for specific applications.
3. How does the ARS grade differ from the ACS grade in this product?
The ARS (Analytical Reagent Standard) and ACS (American Chemical Society) grades both indicate high purity, but ACS compliance includes additional testing for trace metals and impurities as per ACS specifications.
4. Is this compound compatible with automatic titrators?
Yes, its consistent particle size and high purity make it suitable for use with automatic titrators, provided the instrument is calibrated according to the manufacturer’s guidelines.
5. What precautions should be taken while handling this chemical?
Wear appropriate PPE, including gloves and safety goggles, to avoid skin or eye contact. Work in a well-ventilated area and follow standard lab protocols for handling fine powders.
