A green precipitate forms when dilute sodium hydroxide solution is added to a sample in solution. Identify the metal ion present in the original solution.

The solutions will become cloudy and change color due to the precipitation of metal hydroxides. Add 15M NH4OH with stirring to the same beaker or test tube. The precipitates will dissolve and darkly ...

This is because they're very reactive. When a Group 1 element reacts with water it produces a metal hydroxides solution and hydrogen gas. Let's try it with a lithium. So, on with eye protection ...
