A precipitate forms if the concentrations of the ions in solution in water exceed a certain value, unique to every compound. The more concentrated ammonia pushes the equilibrium even further to the right, lowering the silver ion concentration even more. After varying lengths of time precipitates appear as halide ions (produced from reactions of the halogenoalkanes) react with the silver ions present. WebPotassium BromideBromate, Tenth-Normal (0.1 N) Dissolve 2.78 g of potassium bromate (KBrO3) and 12.0 g of potassium bromide (KBr) in water, and dilute with water to 1000 mL.
