Q
Q: In a titration to determine the presence of chloride ions, which indicator is typically used?
Solution: Potassium Chromate is used as an indicator in titrations involving silver nitrate to detect chloride ions, forming a red precipitate of silver chromate.
Steps: 5
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.
