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.
Using the same reaction, another way to create caesium fluoride is to treat caesium carbonate (Cs 2 CO 3) with hydrofluoric acid and again, the resulting salt can then be purified by recrystallization. The reaction is shown below: Cs 2 CO 3 + 2 HF → 2 CsF + H 2 O + CO 2. CsF is more soluble than sodium fluoride or potassium fluoride in
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.
Dichlorofluoromethane was used as a propellant and refrigerant. Due to its role in ozone depletion, dichlorofluoromethane has been largely phased out.It has ozone depletion potential 0.04.

In 2015, the U.S. Public Health Service, under the Department of Health and Human Services, set the optimal level of fluoride in water at 0.7 milligrams per liter — a level that, after decades ...
TFA is prepared industrially by the electrofluorination of acetyl chloride or acetic anhydride, followed by hydrolysis of the resulting trifluoroacetyl fluoride: [4] CH 3 COCl + 4 HF → CF 3 COF + 3 H 2 + HCl CF 3 COF + H 2 O → CF 3 COOH + HF. Where desired, this compound may be dried by addition of trifluoroacetic anhydride. [5]
