Q: In a titration to identify chloride ions, which indicator is commonly used?
Solution: Chromate is used as an indicator in titrations involving chloride ions, as it forms a colored precipitate with silver ions.
Steps: 5
Step 1: Understand that a titration is a laboratory method used to determine the concentration of a substance in a solution.
Step 2: Identify that chloride ions (Cl-) are the substance we want to measure in this titration.
Step 3: Know that silver ions (Ag+) are commonly used in titrations with chloride ions because they react with chloride to form a solid called silver chloride (AgCl).
Step 4: Learn that an indicator is a substance that changes color to signal the end of a titration.
Step 5: Recognize that chromate (CrO4^2-) is the indicator used in this titration because it forms a colored precipitate (yellow) with silver ions when all the chloride ions have reacted.
