UNII-X3228N20RS - Introduction
Potassium phosphate tribasic, heptahydrate is a chemical substance with the chemical formula K3PO4 · 7H2O. The following is a description of the properties, uses, preparation and safety information of the substance:
Nature:
Potassium phosphate tribasic, heptahydrate is a colorless crystalline solid, soluble in water. It has multiple molecules of crystalline water and therefore takes the form of the heptahydrate. The compound has a melting point of about 55°C and loses water of crystallization upon melting.
Use:
Potassium phosphate tribasic, heptahydrate has many uses in chemical laboratories and industry. It can be used as a buffer to adjust the pH of the solution. In addition, it is often used to formulate chemical fertilizers to provide phosphorus and potassium for plants. Potassium phosphate tribasic, heptahydrate can also be used to prepare other Potassium and phosphate compounds.
Method:
Potassium phosphate tribasic, heptahydrate is usually prepared by reacting phosphoric acid with Potassium hydroxide. First, an appropriate amount of phosphoric acid is dissolved in water, and then potassium hydroxide solution is slowly added, during which precipitation of the intermediate product is observed. Finally, the crystalline solid of Potassium phosphate tribasic, heptahydrate was obtained by filtration and crystallization process.
Security Information:
Potassium phosphate tribasic, heptahydrate is generally considered to be a relatively safe compound. It is less irritating to the skin and eyes at room temperature, but long-term contact should be avoided. During handling and use, care should be taken to avoid inhalation of dust or contact with the skin. When using, follow proper laboratory procedures and use personal protective equipment, such as gloves and goggles. At the time of abandonment, comply with the local prescribed waste disposal methods. If an accident or allergic reaction occurs, seek medical help immediately.
