Questions & Step-by-Step Solutions

Which reagent is commonly used to confirm the presence of sulfate ions in a qualitative analysis?
  • Step 1: Understand that we are looking for a reagent to test for sulfate ions.
  • Step 2: Know that barium chloride is a common reagent used in this test.
  • Step 3: When barium chloride is added to a solution containing sulfate ions, a reaction occurs.
  • Step 4: This reaction produces a white solid called barium sulfate.
  • Step 5: The formation of this white precipitate indicates that sulfate ions are present in the solution.
