Question: In a titration to determine the presence of chloride ions, which indicator is most suitable?

Options:

Correct Answer: Chromate

Solution:

Chromate is used as an indicator in titrations involving chloride ions, as it forms a distinct color change when chloride ions are precipitated.

In a titration to determine the presence of chloride ions, which indicator is most suitable?

Step 1: Understand that a titration is a method used to determine the concentration of a substance in a solution.
Step 2: Identify that we are looking for chloride ions in the solution.
Step 3: Know that an indicator is a substance that changes color to show the presence of certain ions.
Step 4: Learn that chromate is a type of indicator used in this specific titration.
Step 5: Recognize that when chloride ions are present, they react and cause a color change with chromate.
Step 6: Conclude that chromate is the most suitable indicator for detecting chloride ions due to this distinct color change.

Titration – A technique used to determine the concentration of a solute in a solution by reacting it with a reagent of known concentration.
Indicators – Substances that change color at a specific pH or in response to the presence of certain ions, used to signal the endpoint of a titration.
Chloride Ions – Anions (Cl-) that can be detected in solution, often through precipitation reactions.
Precipitation Reaction – A chemical reaction in which two solutions react to form an insoluble solid, known as a precipitate.
