SODIUM DIHYDROGEN CITRATE

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.

The Uses of SODIUM DIHYDROGEN CITRATE

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.

The Uses of SODIUM DIHYDROGEN CITRATE

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

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

Description

Sodium citrate monobasic is a biological buffering agent resistant to changes in pH and sequestrant.
