Answer:

See Explanation

Explanation:

We can establish that there are chloride ions present in water if we add dilute trioxonitrate V acid to a sample of the water in drops followed by aqueous silver trioxonitrate V.

If a white precipitate is observed and the precipitate is found to be soluble in excess aqueous ammonia solution, then we can confirm the presence of chloride ion in the water.
