Fuel Gases: What type of fuel is gas?

The substances in which such ingredients are present which produce heat by acting with oxygen are called fuels. In order to obtain heat from the fuel, initially it is given a small amount of heat in the presence of oxygen from some other source, by doing this, a microscopic part of the fuel reacts with […]

Potassium Alum: Properties, Preparation, Uses

Alum is a double salts and its common formula is R2SO4.M2(SO4)3.24H2O. Where R = A valence metal Such as: K, Na, NH4 M = Tri valent metal Such as: Fe, Al, Cr It is not necessary to write the name of a valence metal in which the potassium is present as a valence metal. Similarly, […]

Anhydrous Aluminium Chloride(AlCl3): Properties, Structure, Uses

Aluminium Oxide:  Al2O3 Aluminium Hydroxide: Al(OH)3 Sodium Meta-aluminate: NaAlO2 Aluminium Sulfate: Al2(SO4)3 Preparation of Aluminium Chloride Anhydrous aluminium chloride is obtained by heating the dry chlorine metal or dry hydrochloric acid gas to the hot aluminium metal and evaporating the vapor. 2Al + 3Cl2 → 2AlCl3 2Al + 6HCl → 2AlCl3 + 3H2 Anhydrous aluminium chloride is […]
