Answer
When dilute nitric acid is added to a solution containing chloride ions, followed by silver nitrate, a white precipitate of silver chloride (AgCl) forms. This is indicative of the presence of chloride ions, as AgCl is insoluble in water.
Step 2

Answer
Qualitative tests are used to identify the presence or absence of a particular substance in a sample, providing information about the type of substances present. In contrast, quantitative tests determine the exact amount or concentration of a substance within a sample, providing numerical data about the quantities involved.
