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.

4 KMnO 4 + 4 KOH → 4 K 2 MnO 4 + O 2 + 2 H 2 O. This reaction illustrates the relatively rare role of hydroxide as a reducing agent. The concentration of K 2 MnO 4 in such solutions can be checked by measuring their absorbance at 610 nm. The one-electron reduction of permanganate to manganate can also be effected using iodide as the reducing ...
The chemical reaction, in which ethylene (C 2 H 4) is oxidised by potassium permanganate (KMnO 4) to carbon dioxide (CO 2), manganese oxide (MnO 2) and potassium hydroxide (KOH), in the presence of water, is presented as follows: [55] 3 C 2 H 4 + 12 KMnO 4 + 2 H 2 O → 6 CO 2 + 2 H 2 O + 12 MnO 2 + 12 KOH

Cyclohexane is a colourless, flammable liquid with a distinctive detergent-like odor, reminiscent of cleaning products (in which it is sometimes used). Cyclohexane is mainly used for the industrial production of adipic acid and caprolactam, which are precursors to nylon. [5] Cyclohexyl (C 6 H 11) is the alkyl substituent of cyclohexane and is ...
A solubility equilibrium exists when a chemical compound in the solid state is in chemical equilibrium with a solution containing the compound. This type of equilibrium is an example of dynamic equilibrium in that some individual molecules migrate between the solid and solution phases such that the rates of dissolution and precipitation are equal to one another.
The following compounds are liquid at room temperature and are completely miscible with water; ... (CH 2) 4 O: tetrahydrofuran: 109-99-9 C 6 H 14 O 4: triethylene ...
