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.
