When Barium Chloride (BaCl2) solution is mixed with Sodium Sulfate (Na2SO4) solution, a white product Barium Sulfate (BaSO4) is formed. This product is known as a ______.
Precipitate
The white product Barium Sulfate formed when Barium Chloride reacts with Sodium Sulfate solution is known as a precipitate.
Isotope, isomer and emulsion describe entirely different chemical or physical concepts, not an insoluble solid formed in a reaction.
Hence, Precipitate is the correct answer.
