Trisodium phosphate dodecahydrate

Description:
Trisodium phosphate dodecahydrate (TSP), with the CAS number 10101-89-0, is an inorganic compound characterized by its crystalline structure and high solubility in water. It appears as a white, granular solid and is commonly used as a cleaning agent, pH buffer, and emulsifier in various industrial applications. The compound consists of three sodium ions (Na⁺) and one phosphate ion (PO₄³⁻), combined with twelve water molecules (H₂O) in its hydrated form. TSP is known for its alkaline properties, making it effective in neutralizing acidic substances and adjusting pH levels in solutions. It is also utilized in food processing as a food additive and in the preparation of certain detergents. While generally considered safe for use in food and cleaning products, it should be handled with care, as it can cause irritation to the skin and eyes upon contact. Additionally, proper disposal methods should be followed to minimize environmental impact.
