What is AgBr? Important knowledge about AgBr.

  1. Definition of AgBr
    AgBr, also known as Silver bromide, is a solid substance that is sparingly soluble in water. It has a molar mass of 187.77 g/mol and a specific gravity of approximately 6.473 g/cm3. The AgBr molecule consists of one silver atom (Ag) and one bromine atom (Br), forming the ions Ag+ and Br-.

  2. Properties of AgBr
    2.1 Physical properties of AgBr
    AgBr is solid, white or pale yellow in color, odorless and its pH cannot be determined due to its insolubility in water.
    2.2 Chemical properties of AgBr
    AgBr is very susceptible to decomposition by light, therefore, it is usually stored in darkness. It can also react with ammonia to form a complex salt.

  3. Common chemical equations involving AgBr
    Metal reaction: AgBr does not typically participate in metal reactions.
    Acid reaction: AgBr can react with some strong acids such as sulfuric acid, nitric acid…
    Nonmetal reaction: AgBr can react with chlorine to form silver chloride.
    Reaction with salts: AgBr can react with some salts such as sodium chloride.

  4. Preparation of AgBr
    4.1 Laboratory synthesis of AgBr
    AgBr is typically prepared through the reaction between sodium bromide and silver nitrate in water.
    4.2 Industrial synthesis of AgBr
    In industry, AgBr is typically produced through the reaction of bromine with excess silver.
