The silver chloride salt can be prepared using the precipitation method.

Add equal volumes of dilute hydrochloric acid to a beaker containing aqueous silver nitrate.

Stir the solution. A white precipitate of silver chloride is formed.

Filter the mixture to obtain silver chloride as the residue. Wash the residue with cold distilled water and dry between two pieces of filter paper.

The copper(II) sulfate salt can be prepared using the filtration method.

Copper(II) oxide is added in excess to a fixed volume of dilute sulfuric acid.

Filter the mixture to remove the excess copper(II) oxide from the copper(II) sulfate solution.

The filtrate of copper(II) sulfate is then heated until saturated.

The saturated solution is allowed to cool so that crystals of copper(II) sulfate can be formed.

Filter the mixture to remove the excess water.

Wash the crystals with a little bit of cold distilled water and dry between two pieces of filter paper.

The sodium chloride salt can be prepared using the titration method.

First, use a pipette to draw an accurate fixed volume of hydrochloric acid to a conical flask.

Add 2 to 3 drops of phenolphthalein into the flask.

Titrate, drop by drop, the sodium hydroxide from the burette into the hydrochloric acid. Swirl the solution each time sodium hydroxide is added to it.

When the first appearance of pink color is observed in the solution, stop the titration and note the volume of sodium hydroxide used.

Mix the exact volume of hydrochloric acid and the required volume of sodium hydroxide, without adding the indicator, to obtain the sodium chloride salt solution.

The salt solution is then heated until saturated.

The saturated solution is allowed to cool so that crystals of sodium chloride can be formed.

Filter the mixture to remove excess water.

Wash the crystals with a little bit of cold distilled water and dry the crystals between two pieces of filter paper.
