The reaction of aqueous solutions of barium chloride and sodium sulfate results in the formation of a precipitation of barium sulfate. Sodium chloride is also formed but is soluble in water. Why would you use filtration to isolate the barium sulfate rather than evaporation or recrystalization? Explain your answer.

Filtration allows the solvent carrying the NaCl tol go through the paper while the paper retains the BaSO4. If the NaCl is allowed to stay with BaSO4 for recrystallization or evaporation then BaSO4 and NaCl will be mixed together.
