Warming amonium chloride with sodium hydroxide in a test is an example of:

When ammonium chloride is heated in a test tube and red litmus is placed at the mouth of the test tube. It first turns blue and then red because

A mixture of chlorides of copper, cadmium, chromium, iron and aluminium was dissolved in water. It was acidified with dilute HCI and then hydrogen sulphide gas was passed for sufficient time. It was filtered, boiled and a few drops of nitric acid were added, while boiling. To this solution, ammonium chloride and ammonium hydroxide were added. To this excess of sodium hydroxide was added and then filtered. The filtrate shall give test for:
