What are Halides?
Halides are binary compounds that are of which one part is an element another part is the halogen atom. A radical is less electronegative compared to that of halogens which form astatine, bromide, fluoride and chloride. Most of the salts are halides. Various halide compounds are tested using silver nitrate solution. Some include Kl, KBr, and KCl.
When halogen reacts with silver nitrate solution, precipitation will be formed, and it varies in colour depending upon the type of halides. Some include Silver Fluoride with no precipitate. Silver Bromide with pale yellow precipitate. Silver Iodide with green precipitate. Silver Chloride with a white precipitate.
Halogen Atom comprising a negative charge is termed as the halide ion. Halide mineral includes halide anion. Fluorite and Halite are two important halide minerals. Fluorite is the main source of hydrogen fluoride. Halite is a primary source of Sodium Chloride. Bischofite forms a primary source of magnesium. Many of the halides are present in the marine evaporite deposits. Few of the halide anions include iodide, bromide, chloride, and fluoride.
Example of Halide Compounds
Organic Halide compounds consist of one or more halogens and belong to a class of synthetic and natural chemicals. Some examples of halide compound include calcium chloride, silver chloride, potassium iodide, potassium chloride, sodium chloride, Iodoform, Chlorine Fluoride, Organohalides, Bromoethane and more.
Metal Halides are compounds between a halogen and metals. Some are covalently bond, and some are ionic. Covalently bonded metal ions may form polymeric structures. Metal Halides are formed when all halogens react with metal. It is stated in the below equation.
Uses of Halides
- Halides are used in the solder paste. Halogens are incorporated into organohalides compounds in synthetic organic chemistry.
- It is widely used in metal halide lamps that are high-intensity discharge lamps. They are used as a supplement to provide sunlight in a rainy climate or a greenhouse.
- Silver halides are used in the papers and phosphoric films.
