The halogens can all react with metals to form metal halides according to the following equation: 2M + nX 2 → 2MX n. where M is the metal, X is the halogen, and MX n is the metal halide. Sample of silver chloride. In practice, this type of reaction may be very exothermic, hence impractical as a preparative technique.
Many salts are halides; the hal-syllable in halide and halite reflects this correlation. All Group 1 metals form halides that are white solids at room temperature. [2] A halide ion is a halogen atom bearing a negative charge. The common halide anions are fluoride (F −), chloride (Cl −), bromide (Br −), and iodide (I −).
Alkali metal halides, or alkali halides, are the family of inorganic compounds with the chemical formula MX, where M is an alkali metal and X is a halogen. These compounds are the often commercially significant sources of these metals and halides. The best known of these compounds is sodium chloride, table salt. [1]
Metal halides are compounds between metals and halogens. Some, such as sodium chloride are ionic , while others such as uranium hexafluoride have considerable covalent character to their bonding. This category serves as a complement to Category:Nonmetal halides
All of the stable alkali metal halides have the formula MX where M is an alkali metal and X is a halogen. They are all white ionic crystalline solids that have high melting points. [5] [84] All the alkali metal halides are soluble in water except for lithium fluoride (LiF), which is insoluble in water due to its very high lattice enthalpy.
The alkaline earth metals all react with the halogens to form ionic halides, such as calcium chloride (CaCl 2 ), as well as reacting with oxygen to form oxides such as strontium oxide ( SrO ). Calcium, strontium, and barium react with water to produce hydrogen gas and their respective hydroxides (magnesium also reacts, but much more slowly ...
The metal is not attacked by sulfuric or hydrochloric acids. It dissolves in nitric acid with the evolution of nitric oxide gas to form dissolved Pb(NO 3) 2. [8] It is a well-soluble solid in water; it is thus a key to receive the precipitates of halide, sulfate, chromate, carbonate, and basic carbonate Pb 3 (OH) 2 (CO 3) 2 salts of lead. [3]
A silver halide (or silver salt) is one of the chemical compounds that can form between the element silver (Ag) and one of the halogens.In particular, bromine (Br), chlorine (Cl), iodine (I) and fluorine (F) may each combine with silver to produce silver bromide (AgBr), silver chloride (AgCl), silver iodide (AgI), and four forms of silver fluoride, respectively.
