Caesium bromide or cesium bromide is an ionic compound of caesium and bromine with the chemical formula CsBr. It is a white or transparent solid with melting point at 636 °C that readily dissolves in water.
Sodium iodide (chemical formula NaI) is an ionic compound formed from the chemical reaction of sodium metal and iodine. Under standard conditions, it is a white, water-soluble solid comprising a 1:1 mix of sodium cations (Na +) and iodide anions (I −) in a crystal lattice. It is used mainly as a nutritional supplement and in organic chemistry.
With chlorine, monochloramine is formed. Pentavalent ammonia is known as λ 5-amine, nitrogen pentahydride decomposes spontaneously into trivalent ammonia (λ 3-amine) and hydrogen gas at normal conditions. This substance was once investigated as a possible solid rocket fuel in 1966. [45] Ammonia is also used to make the following compounds:
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.
An electrolyte is a substance that conducts electricity through the movement of ions, but not through the movement of electrons. [1] [2] [3] This includes most soluble salts, acids, and bases, dissolved in a polar solvent like water. Upon dissolving, the substance separates into cations and anions, which disperse uniformly throughout the ...
A chemical substance is a unique form of matter with constant chemical composition and characteristic properties. [1] [2] Chemical substances may take the form of a single element or chemical compounds. If two or more chemical substances can be combined without reacting, they may form a chemical mixture. [3]
Although most compounds are referred to by their IUPAC systematic names (following IUPAC nomenclature), traditional names have also been kept where they are in wide use or of significant historical interests.
Zinc nitrate is an inorganic chemical compound with the formula Zn(NO 3) 2. This colorless, crystalline salt is highly deliquescent. It is typically encountered as a hexahydrate Zn(NO 3) 2 ·6H 2 O. It is soluble in both water and alcohol.
