explain the reaction and principle involved in assay of sodium chloride

Describe a chemical test to show that the sodium chloride solution contains chloride ions.

When sodium reacts with chlorine, sodium chloride is produced. Andrew represented this reaction with this equation:Na + Cl2 → 2NaClThe equation is because the number of atoms is on both sides of the arrow.

Sodium hydroxide solution (in water) reacts with hydrochloric acidsolution (in water) to produce sodium chloride solution and water

What happens when sodium undergoes a chemical reaction with chlorine?

How many chloride ions are present arounda sodium ion in the sodium chloride crystal ?
