The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise.
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.
A supersaturated solution of sodium acetate in water is supplied with a device to initiate crystallization, a process that releases substantial heat. Solubility from CRC Handbook. Sodium acetate trihydrate crystals melt at 58–58.4 °C (136.4–137.1 °F), [12] [13] and the liquid sodium acetate dissolves in the released water of crystallization.
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
For example, the Kamlet-Taft parameters are dipolarity/polarizability (π*), hydrogen-bonding acidity (α) and hydrogen-bonding basicity (β). These can be calculated from the wavelength shifts of 3–6 different solvatochromic dyes in the solvent, usually including Reichardt's dye , nitroaniline and diethylnitroaniline .
Neodymium(III) acetate as a hydrate is a purple solid that is soluble in water. [9] [6] The solubility of the compound increases when sodium acetate is added, forming a blue complex. [10] It forms crystalline hydrates [9] in the composition of Nd(CH 3 COO) 3 ·nH 2 O, where n = 1 and 4 are red-violet crystals that lose water at 110 °C.
Sodium chloroacetate is a common laboratory reagent in organic chemistry as illustrated by many entries in the book series Organic Syntheses. With bifunctional nucleophiles, sodium chloroacetate is a precursor to heterocycles. [4] [5] Reaction with sodium nitrite give nitroacetic acid. [6] With sodium ethoxide it gives ethoxyacetate. [7]
