Questions & Step-by-Step Solutions

In qualitative analysis, which reagent is commonly used to test for the presence of sulfate ions?
  • Step 1: Understand that we are looking for a reagent to test for sulfate ions in a solution.
  • Step 2: Identify that barium chloride is the common reagent used for this test.
  • Step 3: Add barium chloride to the solution that may contain sulfate ions.
  • Step 4: Observe the reaction; if sulfate ions are present, a white solid will form.
  • Step 5: This white solid is barium sulfate, confirming the presence of sulfate ions.
