Description
- General description: Sodium phosphate is a colorless crystalline sodium salt. It is widely used as a buffer in molecular biology, biochemistry, and chromatographic studies. It exists in three forms: monobasic (NaH2PO4), dibasic (Na2HPO4), and tribasic (Na3PO4). Monobasic and dibasic forms in varying ratios are commonly used to compose the neutral sodium phosphate buffer solution.
- Application: Sodium phosphate dibasic dodecahydrate may be used to prepare the 0.1M phosphate buffer having pH 7.4.[1]
