TRISODIUM PHOSPHATE
Trisodium phosphate (TSP) is a white, crystalline solid with the chemical formula Na3PO4. It is highly soluble in water, with a solubility of approximately 1 g in 4 mL of water at room temperature. TSP has a density of about 1.62 g/cm³ and melts at 73.4°C (164.1°F). It is hygroscopic, meaning it readily absorbs moisture from the air, which can affect its physical form and properties over time. In its solid state, TSP is stable under normal conditions but decomposes at higher temperatures, releasing sodium oxide and phosphorus pentoxide. This compound is commonly used in cleaning agents, water treatment, and food processing due to its alkalinity and ability to emulsify oils.
