Citric acid trisodium salt E331 sodium citrate tertiary trisodium citrate. 

Sodium citrate dihydrate consists of odorless, colorless, monoclinic crystals, or a white crystalline powder with a cooling, saline taste. It is slightly deliquescent in moist air, and in warm dry air it is efflorescent. Although most pharmacopeias specify that sodium citrate is the dihydrate, the USP 28 states that sodium citrate may be either the dihydrate or anhydrous material.

Sodium citrate, as either the dihydrate or anhydrous material, is widely used in pharmaceutical formulations see Table I.

In another spectrophotometric procedure Motomizu [224] adds to the sample (2 litres) 40% (w/v) sodium citrate dihydrate solution (10 ml) and a 0.2% solution of 2-ethylamino-5-nitrosophenol in 0.01 M hydrochloric acid (20 ml). After 30 min, add 10% aqueous EDTA (10 ml) and 1,2-dichloroethane (20 ml), mechanically shake the mixture for 10 minutes, separate the organic phase and wash it successively with hydrochloric acid (1 2) (3 x 5 ml), potassium hydroxide (5 ml), and hydrochloric acid (1 2) (5 ml). Filter, and measure the extinction at 462 nm in a 50 mm cell. Determine the reagent blank by adding EDTA solution before the citrate solution. The sample is either set aside for about 1 day before analysis (the organic extract should then be centrifuged), or preferably it is passed through a 0.45 xm membrane-filter. The optimum pH range for samples is 5.5 - 7.5. From 0.07 to 0.12 p,g/l of cobalt was determined there is no interference from species commonly present in seawater.

Solution Preparation. Solutions were prepared from reagent grade citric acid monohydrate, sodium citrate dihydrate, NaHS03, Na2S04, NaCl, and standardized NaOH solution. Hydroquinone (0.1 wt %) was added to inhibit oxidation of solutions with NaHS03. 

While continuing to mix the solution, the para-ben/glycol solution, the remaining propylene glycol, artificial strawberry flavor, artificial banana flavor, saccharin sodium, citric acid anhydrous, and sodium citrate dihydrate are added and mixed until dissolved.
