Описание
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.

Использование
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.
Подготовка
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).
Общее описание
Sodium citrate is a useful setting retardant for improvement of properties of brushite cement.
