Help: Preparation of silver nitrate in ammonia solution
Thread Content
Silver nitrate in ammonia solution is needed for solution preparation; ask how to prepare silver nitrate in ammonia
Chemical formula: OH·xH2O. Preparation method: 1. Prepare a test tube: First, add a small amount of NaOH solution to the test tube, shake it, and then heat it to boiling. After pouring out the NaOH, wash it with distilled water and set it aside. 2. Prepare the solution: Pour 1 mL of AgNO3 solution into a cleaned test tube, then add ammonia solution drop by drop while shaking, until the precipitate formed initially dissolves completely.
Ammonia water is added to the silver nitrate solution (added drop by drop until complete dissolution), and then a certain amount of ammonia water is added to complete the process. This solution must not be left as is
