Specification
The Silver bromide, with the CAS registry number 7785-23-1, is also known as Silver monobromide. It belongs to the product categories of Inorganics; Catalysis and Inorganic Chemistry; Chemical Synthesis; Silver; SilverMetal and Ceramic Science; Crystal Grade Inorganics; Metal and Ceramic Science; Salts; Silver Salts; Metal halide. Its EINECS number is 232-076-8. This chemical's molecular formula is AgBr and molecular weight is 187.77. What's more, its systematic name is silver(1+) bromide. You should not breathe dust. When using it, you must avoid contact with eyes. It should be sealed and stored in a cool and dry place. Moreover, it should be protected from oxides, light and amine. It is a soft, pale-yellow, water insoluble salt well known for its unusual sensitivity to light. It is used to determine trace rubidium. It is used to manufacture photo film or sensitive paper. It is also used as an analysis reagent.
Physical properties of Silver bromide are: (1)ACD/LogP: 0.00; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 0; (4)ACD/LogD (pH 7.4): 0; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1; (7)#H bond acceptors: 0; (8)#H bond donors: 0; (9)#Freely Rotating Bonds: 0; (10)Enthalpy of Vaporization: 19.92 kJ/mol; (11)Vapour Pressure: 20200 mmHg at 25°C.
Preparation: this chemical can be prepared by adding alkali bromide solution (typically potassium bromide) to the nitric acid silver solution gradually, then precipitations are generated. Washing the precipitations with hot water repeatedly, then the product is got. It must be proceeded in the dark room or red light. Modern preparation of a simple, light-sensitive surface involves forming an emulsion of silver halide crystals in a gelatine, which is then coated on a film or other support. The crystals are formed by precipitation in a controlled environment to produce small, uniform crystals called grains.
