Sodium acetate trihydrate crystals melt at 58–58.4 °C (136.4–137.1 °F), [14] [15] dissolving in their water of crystallization [citation needed]. When they are heated past the melting point and subsequently allowed to cool, the aqueous solution becomes supersaturated .
Sodium thiosulfate (sodium thiosulphate) is an inorganic compound with the formula Na 2 S 2 O 3 ·(H 2 O) x. Typically it is available as the white or colorless pentahydrate (x = 5), which is a white solid that dissolves well in water. The compound is a reducing agent and a ligand, and these properties underpin its applications. [2]
An acetate is a salt formed by the combination of acetic acid with a base (e.g. alkaline, earthy, metallic, nonmetallic or radical base). "Acetate" also describes the conjugate base or ion (specifically, the negatively charged ion called an anion) typically found in aqueous solution and written with the chemical formula C 2 H 3 O − 2.
The thawing effect of the solid sodium formate can even be increased by moistening with aqueous potassium formate or potassium acetate solutions. The degradability of sodium formate is particularly advantageous with a chemical oxygen demand (COD) of 211 mg O 2 /g compared with the de-icing agents sodium acetate (740 mg O 2 /g) and urea with ...
Thioglycolic acid ( TGA) is the organic compound HSCH 2 CO 2 H. TGA is often called mercaptoacetic acid (MAA). It contains both a thiol ( mercaptan) and carboxylic acid functional groups. It is a colorless liquid with a strongly unpleasant odor. [4] [5] TGA is miscible with polar organic solvents.
Trisodium citrate has the molecular formula Na 3 C 6 H 5 O 7. It is sometimes referred to simply as "sodium citrate", though sodium citrate can refer to any of the three sodium salts of citric acid. It possesses a saline, mildly tart flavor, and is a mild alkali .
Ammonium acetate, also known as spirit of Mindererus in aqueous solution, is a chemical compound with the formula NH 4 CH 3 CO 2. It is a white, hygroscopic solid and can be derived from the reaction of ammonia and acetic acid .
Zinc acetate is a salt with the formula Zn (CH 3 CO 2) 2, which commonly occurs as the dihydrate Zn (CH 3 CO 2) 2 ·2H 2 O. Both the hydrate and the anhydrous forms are colorless solids that are used as dietary supplements. When used as a food additive, it has the E number E650.
