Abstract Silver nitrate solution was prepared by the commercially available reagents. It remained transparent while ammonia water was added dropwise, which was caused by the existence of trace impurity ammonium nitrate in the silver nitrate reagents. In the reaction of silver nitrate solution with ammonia water, the product mainly was silver ammonia complex, and a little mid-product silver oxide, by the mass determination of silver oxide precipitation in the reaction. Furthermore, the problem was also explained that the product was transparent solution or white precipitation while ammonia water being added dropwise into silver nitrate solution.
