How To Test For Positive Ions - Part 2

The video tutorial explains how to test for the presence of metal ions and the ammonium ion using various methods. It covers the flame test for group 1 and 2 metal ions and copper ions, and the use of sodium hydroxide to identify transition metal ions by observing the color of the precipitate formed. The tutorial also discusses the oxidation process of iron hydroxide and how to test for non-transition metal ions like calcium, aluminum, and magnesium. Additionally, it describes the procedure to test for the ammonium ion by forming ammonia, which can be detected using litmus paper or by forming ammonium chloride smoke.
