Trisodium phosphate (TSP) is the inorganic compound with the chemical formula Na3PO4. It is a white, granular or crystalline solid, highly soluble in water, producing an alkaline solution.
Formula: Na₃PO₄
Molecular Weight: 163.94 g/mol
Appearance: Trisodium phosphate is typically a white, crystalline or granular solid. It is highly soluble in water.
Solubility: It dissolves easily in water to form an alkaline solution.
pH: When dissolved in water, trisodium phosphate forms a strongly alkaline solution, typically around pH 12. This high pH makes it a strong base.
Density: About 1.62 g/cm³ (solid).
Melting Point: The melting point of trisodium phosphate is approximately 73.4°C (164°F), and it decomposes at higher temperatures.
Cleaning Agent: TSP is a powerful cleaning agent and is often used in industrial and household cleaners. It is effective in removing grease, oils, and stains from surfaces.
Water Treatment: It is used in water treatment plants to control pH levels and to prevent corrosion in boilers and cooling systems. It also helps in softening water by removing calcium and magnesium ions.
Food Processing: Trisodium phosphate is used in food processing as an emulsifier, acidity regulator, and preservative. It can be used to maintain the consistency of processed foods like cheese and meat products.
Detergents: In laundry and dishwasher detergents, trisodium phosphate is used as a builder, helping to soften water and enhance the effectiveness of the detergent.
pH Control and Buffers: Due to its alkaline nature, TSP is used to prepare buffering solutions in laboratory settings and is often a component in phosphate buffer solutions (PBS), commonly used in biological research and molecular biology.
Handling: Trisodium phosphate should be handled with caution in a well-ventilated area. Use protective equipment to avoid direct contact with skin and eyes. Avoid generating dust and inhaling any vapors or particulate matter.
Storage: Store in a cool, dry place, away from moisture, as it is hygroscopic and will absorb water. Keep the container tightly sealed to avoid contamination.
