웹The barium hydroxide will split into one barium ion, Ba^(2+), and two hydroxide ions, OH-. And the hydrochloric acid will split into one hydrogen ion, H+, and one chloride ion, Cl-. At this point the reaction becomes a double replacement reaction essentially where the hydroxide and hydrogen ions combine to form water, OH- + H+ = H2O. 웹2014년 1월 23일 · Q18. What mass of barium sulfate will be precipitated when 125 mL of a 0.20 M solution of barium chloride is mixed with 200 mL of a 0.17 M solution of sodium sulfate. (Hint: work out which reagent is limiting.) BaCl 2 + Na 2SO 4 → BaSO 4 + 2NaCl Amount of = BaCl 2 = 0.20 × 0.125 = 0.025 mol Amount of = Na 2SO 4 = 0.17 × 0.200 = 0.034 mol
