- Definition of BaS
BaS, also known as Barium Sulfide, is an inorganic chemical with the formula BaS. The English name for it is Barium sulfide. In this formula, Ba represents the element Barium with an atomic mass of 137.33, and S stands for a sulfur atom with an atomic mass of 32.07. The structure of the BaS molecule consists of one Ba^2+ ion and one S^2- ion.
- Characteristics of BaS
2.1 Physical properties of BaS: BaS usually exists as a fine powder, black or dark brown in color, with no distinctive odor. This substance has a neutral pH level.
2.2 Chemical properties of BaS: BaS easily reacts with acids to form salts and hydrogen sulfide. It can also react to form barium oxide and sulfur when exposed to air.
- Common chemical equations of BaS:
3.1 Reaction with metals: BaS does not typically react with metals.
3.2 Reaction with acids: BaS + 2HCl -> BaCl2 + H2S
BaS + H2SO4 -> BaSO4 + H2S
3.3 Reaction with non-metals: BaS + O2 -> BaSO4
3.4 Reaction with salts: BaS does not typically react with salts.
- Preparation of BaS:
4.1 Laboratory preparation: BaS can be prepared by heating barium with sulfur.
4.2 Industrial preparation: In industry, BaS is usually produced by reducing barium sulfate (BaSO4) with coal at high temperatures.
