Interhalogen compounds are generally covalent compounds in which the larger halogen forms the central atom. Type AX. As excepted, the compounds of the type AX…

Uses of Fluorine: Fluorine is used in the manufacture of a series of compounds known as freons. These non-toxic, non-combustible and volatile liquids are used…

Fluorine does not occur free in nature. It occurs in the combined form. This was devised by Dennis, Veeder and Rochow in 1931. Symbol –…

Laboratory Preparation of Etching Glass: Industrially, hydrogen fluoride is obtained by heating fluorspar (CaF2) with concentrated H2SO4 in a lead vessel. CaF2 + H2SO4 →…

Fluorine differs from the rest of the elements of its family due to (i) its small size (ii) highest electronegativity, (iii) low bond dissociation energy,…

Hydrides of the Halogens (Hydrogen halides): i) All halogens react with hydrogen to form volatile covalent hydrides of formula HX. ii) These hydrides are called…

Chemical Properties of HALOGEN 1. Oxidizing power: An important feature of the halogen is their oxidizing property which is due to high electron affinity of…

Effect of pressure on solubility: Pressure: There is no effect of temperature on solubility of solid or liquid solute in a liquid solvent. But if…

Effect of temperature on solubility: Temperature: In solid substance solubility is related with temperature. Generally if the temperature is increased the solubility of solid substance…

Phosphine (PH3) is the best-known hydride of phosphorus. It is created in the soil by the bacterial decline of phosphates. It is a compound which…
