SODIUM DIHYDROGEN CITRATE Chemical Properties,Uses,Production
Description
Mono sodium citrate, or sodium dihydrogen citrate, is an acid salt with the chemical formula NaH2C6H5O7, or C3H4OH(COOH)2COONa. Since it has two remaining open spots on the citrate anion, it is used as a relatively strong sequestrant. It is used to prevent platelet clumping in blood samples. It is one of the 3 citric acid salts.
Chemical Properties
white crystalline powder
Uses
Sodium dihydrogencitrate has been employed:
- as reductant and stabilizer during the synthesis of Fe3O4 Pt core/shell particles
- in characterization of carbon-based electrode materials as cathode in half-cell configuration
- in electrochemical reduction of proton at carbon fiber electrode in the presence and absence of Pt nanoparticles
Uses
Sodium dihydrogen citrate acts as a buffering agent and sequestrant. It is also employed as a reductant and stabilizer in the preparation of b>Fe3O4 platinum core/shell particles. Further, it is used in electrochemical reduction of proton at carbon fiber electrode in the presence and absence of platinum nanoparticles. In addition to this, it plays a useful role in characterization of carbon-based electrode materials as cathode in half-cell configuration.
Preparation
Monosodium citrate can be prepared by the direct reaction of sodium carbonate or bicarbonate with citric acid:
NaHCO3(s) + C6H8O7 (aq) → NaC6H7O7 (aq) + CO2 (g) + H2O (l).
General Description
Sodium citrate is a useful setting retardant for improvement of properties of brushite cement.
Flammability and Explosibility
Non flammable
