Sodium acetate trihydrate crystals melt at 58–58.4 °C (136.4–137.1 °F), [12] [13] 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 .
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
BSS (ophthalmic irrigation solution) (produced by Alcon) . Composition per 1 mL: sodium chloride (NaCl) 6.4 mg, potassium chloride (KCl) 0.75 mg, calcium chloride dihydrate (CaCl 2 ·2H 2 O) 0.48 mg, magnesium chloride hexahydrate (MgCl 2 •6H 2 O) 0.3 mg, sodium acetate trihydrate (C 2 H 3 NaO 2 ·3H 2 O) 3.9 mg, sodium citrate dihydrate (C 6 H 5 Na 3 O 7 ·2H 2 O) 1.7 mg, sodium hydroxide ...

The dissociation of salts by solvation in a solution, such as water, means the separation of the anions and cations. The salt can be recovered by evaporation of the solvent. An electrolyte refers to a substance that contains free ions and can be used as an electrically conductive medium.
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 ...
Also described as the sodium acid salt of acetic acid, it is best described as the sodium salt of the hydrogen-bonded anion (CH 3 CO 2) 2 H −. The O···O distance is about 2.47 angstrom. [2] The species has no significant existence in solution but forms stable crystals.
Tetrasodium EDTA is the salt resulting from the neutralization of ethylenediaminetetraacetic acid with four equivalents of sodium hydroxide (or an equivalent sodium base). It is a white solid that is highly soluble in water. Commercial samples are often hydrated, e.g. Na 4 EDTA. 4H 2 O. The properties of solutions produced from the anhydrous ...
