Physicochemical Properties
- Molecular weight: 163.94 g/mol
- Appearance: white crystalline or powdery solid
- Odor: Odorless or slightly sulphide odor
- Density: 1.62 g/cm³ (dodecahydrate, 20°C)
- Melting point: approx. 73.4°C (dodecahydrate decomposition)
- Chemical Safety: Unrestricted goods
- Solubility: Water: easily soluble in water, aqueous solution is strongly alkaline (pH about 12); Organic solvent: insoluble in ethanol, and other organic solvents
- Hydrolysis reaction: Fully ionized in water to form phosphate ions and sodium ions
- Complexation: Form an insoluble precipitate with metal ions (e.g. Ca² +, Mg² +) for softening hard water
- Thermal stability: It decomposes when heated to high temperatures, forming sodium phosphate and oxygen
- Acid base: The aqueous solution is strongly basic and can react with acid to form phosphate
Applications of Potassium Dihydrogen Phosphate
1. Agriculture
Efficient fertilizer: Potassium dihydrogen phosphate is a high concentration phosphorus potassium compound fertilizer, which can provide phosphorus (P) and potassium (K) two key nutrients for plants.
- Suitable for foliar spraying, drip irrigation or soil application to promote crop growth, flowering and fruit
- Often used in fruit trees, vegetables, flowers and other high value-added crops
- Advantages: good water solubility, high absorption efficiency, no residue to the soil
2. Medicine and Cosmetics
- Buffer: In pharmaceuticals and cosmetics, used as a buffer to regulate pH
- Nutritional supplements: For the preparation of drugs containing phosphorus and potassium, such as electrolyte supplements
- Stabilizers: In cosmetics, help stabilize the formula and prevent ingredients from breaking down
3. Industrial Use
- Water treatment: Corrosion inhibitor for boiler water and cooling water treatment to prevent corrosion of metal equipment
- Water softener: Combined with calcium and magnesium ions to prevent scale formation
- Flame retardants: Used for flame retardant treatment of wood, textiles and plastics
- Electroplating additives: Used in the electroplating industry to regulate the pH value and conductivity of electroplating solutions
4. Research and Laboratories
- Buffer solution: Common reagent for preparing buffer solutions, widely used in biochemistry and molecular biology experiments
- Analytical reagent: Used in chemical analysis as a standard substance or reagent
- Medium component: In microbial culture, as a source of phosphorus and potassium
