When dilute nitric acid is added to Cl- ions, the resulting reaction often leads to the formation of a white precipitate of silver chloride (AgCl) when silver nitrate is also present in the solution. However, since the question specifically refers to the behavior of Cl- ions in diluted nitric acid, it's important to note that nitric acid does not react directly with chloride ions in a way that produces a colored solution or significant precipitate.

In practice, the addition of dilute nitric acid mostly serves to provide an acidic environment and can help with the solubility of certain salts. Chloride ions (Cl-) themselves remain in solution without forming a precipitate. The reaction that often comes to mind with chloride involves silver ions, leading to the formation of a white precipitate if those ions are present. Therefore, under typical laboratory contexts where chloride ions interact with silver nitrate in the presence of dilute nitric acid, a white precipitate is expected.

The other potential outcomes of this reaction do not accurately represent the interactions that occur when chloride ions react with dilute nitric acid, making the formation of a white precipitate the most relevant and correct result associated with these ions when additional reactants are considered.
