potassium hydrogen phthalate boiling point is the temperature at which potassium hydrogen phthalate will begin to boil. The boiling point of KHP is typically around 250 deg C, although it can reach higher temperatures under certain conditions.
Aqueous solubility of KHP is moderate to high, with a pH range from 3.5 to 9.5. It is a common acid-base buffer for acid-base titrations, pH meter calibration, and total organic carbon testing.
Chemical Name: Potassium Hydrogen Phthalate (KHP) Formula: C8H5KO4 Density: 1.10 g/cm3 Appearance: Crystalline Powder Characteristics: Moderate Soluble in Water, Stable in Air, Non-Hygroscopic and not affected by oxygen or carbon dioxide.
The potassium element is a silvery gray metal with an acidic odor and properties that are characteristic of alkali compounds. It is a component of many important compounds and is used in a wide variety of industrial and chemical processes.
Reagent grade potassium hydrogen phthalate is manufactured by American Elements in accordance with ASTM specifications, and is available in a wide variety of volume sizes. It is also offered in high purity, submicron and nanopowder forms.
ACS Reagent Grade standards are supplied in a standard or resealable container, and are labeled with the appropriate ACS logo. All products are subject to verification of compliance with applicable ACS, Reagent, and Technical Grade specifications before shipping.
Accuracy of titrations performed with this substance is primarily dependent on the adherence to specified sample weights and final titration volumes during all weighing, transfer, and titration operations. It is also recommended that titrations be repeated at least in duplicate on both the sample and the NIST SRM potassium hydrogen phthalate to establish a reliable correlation between the two results.
