Disodium citrate, also known as disodium hydrogen citrate, (Neo-Alkacitron) and sesquihydrate, is an acid salt of citric acid with the chemical formula Na 2 C 6 H 6 O 7. [2] It is used as an antioxidant in food and to improve the effects of other antioxidants.
Sodium citrate is the citric acid-based sodium salt. This is often referred to as sour salt, and is primarily used as a food additive, typically for flavour or preservative purposes. It gives both the sour and salty flavours of club soda.
1 sty 2014 · Disodium hydrogen citrate and potassium dihydrogen citrate behave similarly at low concentrations with ν ~ 3, but sodium dihydrogen citrate is dissociated only to Na + and H 2 Cit − having ν ≤ 2 (Fig. 5.5). In all cases, sodium salts have lower value of ν than corresponding potassium salts.
Polyatomic ions are covalent units (molecules) where the total number of protons \(\neq\) to the total number of electrons and they were introduced in section 2.6.4.2. They end in [-ide], [-ate] and [-ite].
1 lip 2016 · Abstract. The crystal structure of disodium hydrogen citrate sesquihydrate, 2Na 2 + ·C 6 H 6 O 7 2− ·1.5H 2 O, has been solved and refined using laboratory X-ray single-crystal diffraction data, and optimized using density functional techniques.
Chemical: Sodium dihydrogen citrate. Green circle - The chemical has been verified to be of low concern based on experimental and modeled data.
1 sty 2014 · Using values of the ionization product of water K w, the dissociations constants of citric acid, K 1, K 2 and K 3, the corresponding citrate ions sizes and a (Na +) = 5.0 Å, the distribution of individual species as a function of total concentration of sodium dihydrogen citrate at 25 °C is illustrated in Fig. 3.2.
