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.
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
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.
Dichloromethane (DCM, methylene chloride, or methylene bichloride) is an organochlorine compound with the formula C H 2 Cl 2. This colorless, volatile liquid with a chloroform-like, sweet odor is widely used as a solvent. Although it is not miscible with water, it is slightly polar, and miscible with many organic solvents.

It can be prepared by reacting carbon tetrachloride with hydrogen fluoride in the presence of a catalytic amount of antimony pentachloride: CCl 4 + 2HF → CCl 2 F 2 + 2HCl This reaction can also produce trichlorofluoromethane (CCl 3 F), chlorotrifluoromethane (CClF 3 ) and tetrafluoromethane (CF 4 ).
Sodium fluoride: yellow is fluorine, purple is sodium. They are isoelectronic, but fluorine is bigger because its nuclear charge is lower. The alkali metals form monofluorides. All are soluble and have the sodium chloride (rock salt) structure, [47] Because the fluoride anion is basic, many alkali metal fluorides form bifluorides with the ...

Electrophilic fluorinating reagents could in principle operate by electron transfer pathways or an S N 2 attack at fluorine. This distinction has not been decided. [2] By using a charge-spin separated probe, [3] it was possible to show that the electrophilic fluorination of stilbenes with Selectfluor proceeds through an SET/fluorine atom transfer mechanism.
