When solutions of silver nitrate and potassium bromide are mixed, a pale yellow precipitate is formed. A pale-yellow precipitate is produced in the reaction between aqueous silver nitrate and potassium bromide solutions. Decomposition reactions require energy either in the form of heat or light or electricity for breaking down the reactants. Lets start with the reactants. This prevents unreacted hydroxide ions reacting with the silver ions.
