Preparation of Monosodium citrate: 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)
Since Monosodium citrate 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.
