a) lithium

Execution:

First, a magnesia stick is dipped in hydrochloric acid and then in lithium chloride. The stick is then held in the burner flame.

Observation:

The flame turns carmine.

b) ammonium ion

Execution:

Some ammonium sulfate is placed in a small vessel. A strip of indicator paper is moistened and stuck to the inside of a watch glass case. Then a few drops of hydrochloric acid are added to the ammonium sulfate and the watch glass bowl is held over the vapors that develop.

Observation:

The indicator paper turns blue because gaseous ammonia is produced, which reacts with the water in the indicator paper to form a base.

c) sulfate ions

Execution:

The ammonium sulfate is dissolved in water and treated with barium chloride solution.

Observation:

A white, poorly soluble precipitate of barium sulfate is formed.

d) presence of water

Execution:

Anhydrous copper sulfate, which is white, is added to the substance to be tested.

Observation:

In the presence of water, the salt turns light blue.

e) carbonate ions

Execution:

A few drops of hydrochloric acid are placed on the solid calcium carbonate.

Observation:

A gas evolution can be observed, during which carbon dioxide is produced.

f) iodide ions

Execution:

A potassium iodide solution is mixed with silver nitrate solution.

Observation:

A yellow precipitate of silver iodide is formed.
