QuestionAnswer
Chemical used to test for chloride ions AgNO3 (White precipitate, AgCl, is formed)
Chemical used to test for Sulfate(SO4) & Sulfite(SO3) ions BaCl2 (White precipitate, BaSO4/BaS03, is formed)
Chemical used to differentiate between BaSO4 & BaS03 Dilute HCl
Does Barium Sulphate or Sulphite dissolve in HCl? Barium Sulphite dissolves
Chemical used to test for Carbonate(CO3) & Hydrogen Carbonate (HC03) ions Add dilute HCl, if the gas given off makes limewater cloudy C03/HCO3 is present
Chemical used to differentiate between HC03 & C03 MgS04
Does MgS04 react with HCO3 or CO3 to give a white precipitate? C03, however boiling HC03 with MgSO4 gives a precipitate
