Laboratory Preparation of Xenon Fluoride Compounds
Xenon forms three binary Fluorides XeF2, XeF4, and XeF6 by the direct union of elements under appropriate experimental conditions. PROPERTIES: Xe F2, Xe F4 and…
Why Silver Fluoride is Soluble in Water but Silver Chloride not Soluble?
Ionic compounds are generally soluble in polar solvents like water, covalent compounds are not. So if the anion of any salt is very much polarized,…
Structures of Interhalogen Compounds
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
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…
Isolation of Fluorine
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
Laboratory Preparation of Etching Glass: Industrially, hydrogen fluoride is obtained by heating fluorspar (CaF2) with concentrated H2SO4 in a lead vessel. CaF2 + H2SO4 →…
What is Melting Point of Formed Compound? Is it Soluble in Water?
The melting and boiling points of NaCI compound are 815°C and 1413°C respectively which is relatively high. NaCl or ionic compounds are soluble in water.…
How bond is formed between Sodium and Chlorine Atoms?
The electronic configurations of sodium and chlorine arc as follows: Na (11) → 1s2 2s2 2p6 3s1 Cl (17) → 1s2 2s2 2p6 3s2 3p5…
What are Necessary Conditions for Formation of Bond?
During the formation of ionic compounds positive and negative ions are formed from neutral atoms and then these oppositely charged ions are held in a…
