Sodium citrate may refer to any of the sodium salts of citric acid (though most commonly the third): . Sodium is the major cation of the extracellular fluid, constituting 90 to 95 per cent of all cations in the blood plasma and interstitial fluid; it thus determines the osmolality of the extracellular fluid. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all ⦠To prepare the stock solutions, dissolve 138 g of NaH 2 PO 4 â¢H 2 O (monobasic; m.w. Example: A buffer solution was made by dissolving 10.0 grams of sodium acetate in 200.0 mL of 1.00 M acetic acid. [4] 0.1 M dibasic sodium phosphate. Mix the volumes shown in the table. Sodium citrate can buffer solutions in the pH range of about 3 to 6.2. Sodium Citrate can perform as a biological buffering agent because it resists changes in pH. An example of the former, a salt is trisodium citrate; an ester is triethyl citrate. What Is Sodium Citrate E331(i)? sodium [so´de-um] a chemical element, atomic number 11, atomic weight 22.990, symbol Na. Phosphate-Citrate Buffer with Sodium Perborate. Other natural salts of citric acid that are used in cosmetics and personal care products include potassium citrate, aluminum citrate, diammonium citrate, ferric citrate, magnesium citrate, monosodium citrate and zinc citrate. Sodium Citrate E331(i) is used to enhance flavor and maintain stability of active ingredients in dairy products and carbonated drinks. Sodium citrate is the sodium salt of citric acid. It has good pH buffering capacity within the range of pH 5.0â7.4. (1962) as a method of avoiding adding additional phosphates to sample preparations.
