Sodium (as sodium citrate)
The sodium version of citric acid is referred to as sodium citrate. It takes the form of a white powder that is crystalline in appearance or white crystals that are granular in appearance and gently liquefy when exposed to humid air. It dissolves easily in water but is almost completely insoluble in alcohol. It has a sour flavour, much like citric acid does. Because of its alkalinizing properties, it has use in the medical field.
