What is Potassium hydrogen phthalate?
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Potassium hydrogen phthalate which has developed particularly rapidly in recent years. Do you know about Potassium hydrogen phthalate?
The official answer:Potassium hydrogen phthalate is an organic compound with the molecular formula C8H5O4K. It is a white crystalline powder, stable in air, soluble in water, and slightly soluble in alcohol, and is used as a buffer for pH determination and as an analytical reference substance.
What’s the application of Potassium hydrogen phthalate?
1.Used as a buffer for pH determination, analytical reference substance, used as analytical reagent and buffer, used as pyrotechnic sounding agent.
2.It is often used as a benchmark substance in analytical chemistry, calibration alkali titration solution. Before use, it needs to be dried at 100~125℃ and prepared for use. It is also used to prepare a standard buffer solution. 0.05 mol/L solution, pH 4.008 at 25℃, such as mixed with hydrochloric acid in a certain ratio, can be prepared with different buffer systems with pH range from 2.2 to 5.5.
