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

Options:

  1. Phenolphthalein
  2. Methyl Orange
  3. Silver Nitrate
  4. Potassium Chromate

Correct Answer: Potassium Chromate

Solution:

Potassium Chromate is used as an indicator in titrations involving silver nitrate to detect chloride ions, forming a red precipitate of silver chromate.

Questions & Step-by-Step Solutions

In a titration to determine the presence of chloride ions, which indicator is typically used?
  • Step 1: Understand that a titration is a method used to determine the concentration of a substance in a solution.
  • Step 2: Know that chloride ions are often tested using silver nitrate in a titration.
  • Step 3: Learn that an indicator is a substance that changes color to show the end point of a titration.
  • Step 4: Identify that potassium chromate is the indicator used in this specific titration.
  • Step 5: Remember that when all the chloride ions react with silver nitrate, the potassium chromate will cause a red precipitate of silver chromate to form, indicating the end of the reaction.
  • Titration – A technique used to determine the concentration of a solute in a solution by reacting it with a solution of known concentration.
  • Indicators – Substances that change color at a specific pH level or in response to a chemical reaction, used to signal the endpoint of a titration.
  • Chloride Ion Detection – The process of identifying the presence of chloride ions in a solution, often through precipitation reactions.
  • Silver Nitrate Reaction – A common reagent used in titrations to react with chloride ions, forming a precipitate.
