Disodium Phosphate (DSP), chemically represented as Na₂HPO₄ and bearing the CAS number 7558-79-4, is more than just a common industrial chemical; it's a fascinating compound with distinct chemical properties that dictate its wide-ranging applications. NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier, delves into the chemistry that makes DSP so valuable.

In aqueous solutions, Disodium Phosphate undergoes partial dissociation, yielding sodium ions (Na⁺) and the dibasic phosphate ion (HPO₄²⁻). This dibasic phosphate ion is amphoteric, meaning it can act as either an acid or a base. Its primary role as a buffering agent stems from its ability to accept or donate protons, effectively stabilizing pH levels. For instance, it can react with strong acids to form phosphoric acid and sodium salts, or with strong bases to form trisodium phosphate. This buffering capacity is critical in applications requiring tight pH control, such as in food processing and chemical synthesis.

Another key chemical behavior of DSP is its capacity to act as a sequestrant. It can chelate or bind with metal ions like calcium and magnesium. This property is leveraged in water treatment to prevent scale formation and in detergents to enhance cleaning efficacy by preventing these ions from interfering with surfactant action. When you are looking to buy Disodium Phosphate that exhibits these precise chemical functionalities, sourcing from a reputable manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. is essential.
