Citric acid sold in a dry powdered form is commonly sold in markets and groceries as "sour salt", due to its physical resemblance to table salt. It has use in culinary applications, as an alternative to vinegar or lemon juice, where a pure acid is needed. Citric acid can be used in food coloring to balance the pH level of a normally basic dye.
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.
The structures of solid magnesium citrates have been characterized by X-ray crystallography.In the 1:1 salt, only one carboxylate of citrate is deprotonated. It has the formula Mg(H 2 C 6 H 5 O 7) 2 The other form of magnesium citrate has the formula Mg(HC 6 H 5 O 7)(H 2 O) 2, consisting of the citrate dianion (both carboxylic acids are deprotonated). [1]
It is also used as an anticoagulant for laboratory testing, in that blood samples are collected into sodium citrate-containing tubes for tests such as the PT (INR), APTT, and fibrinogen levels. Sodium citrate is used in medical contexts as an alkalinizing agent in place of sodium bicarbonate, [2] to neutralize excess acid in the blood and urine ...
Speciation diagram for a 10-millimolar solution of citric acid. The violet curve corresponds to the trisodium citrate. As a conjugate base of a weak acid, citrate can perform as a buffering agent or acidity regulator, resisting changes in pH. It is used to control acidity in some substances, such as gelatin desserts. It can be found in the milk ...
It is also used to increase urine pH (alkalinize urine) - this prevents uric acid stones and cystine stones (which form in cystinuria). [2] It is different from citric acid which is citrate bonded by hydrogen ions (or protons) making it acidic. [3] Citric acid does not alkalinize urine as alkali citrate does. [4]
Monosodium citrate, more correctly, sodium dihydrogen citrate (Latin: natrium citricum acidulatum), is an acid salt of citric acid. Disodium citrate and trisodium citrate are also known. It can be prepared by partial neutralisation of citric acid [3] with an aqueous solution of sodium bicarbonate or carbonate. It has a slightly acidic taste. [3]
Triethyl citrate is an ester of citric acid. It is a colorless, odorless liquid used as a food additive, emulsifier and solvent (E number E1505) [4] to stabilize foams, especially as whipping aid for egg white. [5] It is also used in pharmaceutical coatings and plastics. [6]
