Preparation of Co(NH3)5(ONO)]Cl2

In the hood, heat 160 mL of water to about 80 ˚C in a large beaker with a stir bar. Add 15 mL concentrated ammonia and dissolve 10.0 g [Co(NH3)5Cl]Cl2 in the solution. A slight precipitate of cobalt oxide may form; vacuum filter the solution to remove it. Cool the solution to about 10 ˚C and put it in a cool water bath (cold tap water is OK). Slowly add 2 M HCl with stirring until the solution is neutral to pH paper. Add 10.0 g of sodium nitrite and stir until it dissolves; then add 10 mL of 6 M HCl to precipitate the [Co(NH3)5ONO]Cl2.
