Silver oxide: Solid Ag 2 O −31.1 Silver sulfide: Solid Ag 2 S −31.8 Sodium: Solid Na: 0 Sodium: Gas Na: 107.5 Sodium bicarbonate: Solid NaHCO 3: −950.8 Sodium carbonate: Solid Na 2 CO 3: −1130.77 Sodium chloride: Aqueous NaCl −407.27 Sodium chloride: Solid NaCl −411.12 Sodium chloride: Liquid NaCl −385.92 Sodium chloride: Gas NaCl ...
The vast majority of simple inorganic (e.g. sodium chloride) and organic compounds (e.g. ethanol) are colorless. Transition metal compounds are often colored because of transitions of electrons between d-orbitals of different energy. (see Transition metal#Colored compounds).
Ethylene oxide: A cyclic ether. Also the simplest epoxide. Dimethyl ether: A colourless gas that is used as an aerosol spray propellant. A potential renewable alternative fuel for diesel engines with a cetane rating as high as 56–57. Diethyl ether: A colourless liquid with sweet odour. A common low boiling solvent (b.p. 34.6 °C) and an early ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Industrially, it is mainly produced by the reaction of hydrogen gas with bromine gas at 200–400 °C with a platinum catalyst. However, reduction of bromine with red phosphorus is a more practical way to produce hydrogen bromide in the laboratory: [2] 2 P + 6 H 2 O + 3 Br 2 → 6 HBr + 2 H 3 PO 3 H 3 PO 3 + H 2 O + Br 2 → 2 HBr + H 3 PO 4
An element in a free form has OS = 0. In a compound or ion, the sum of the oxidation states equals the total charge of the compound or ion. Fluorine in compounds has OS = −1; this extends to chlorine and bromine only when not bonded to a lighter halogen, oxygen or nitrogen. Group 1 and group 2 metals in compounds have OS = +1 and +2 ...
Sodium bromide is an inorganic compound with the formula Na Br. It is a high-melting white, crystalline solid that resembles sodium chloride . It is a widely used source of the bromide ion and has many applications.
The bromine test can also be used as an indication of the degree of unsaturation for unsaturated hydrocarbons. Bromine number is defined as gram of bromine able to react with 100g of product. [18] Similar as hydrogenation, the halogenation of bromine is also depend on the number of π bond. A higher bromine number indicates higher degree of ...
