For the following reaction, 5.46 grams of hydrochloric acid are mixed with excess barium hydroxide . Assume that the percent yield of barium chloride is 71.5 %. hydrochloric acid(aq) + barium hydroxide(aq) barium chloride(aq) + water(l) What is the theoretical yield of barium chloride ? grams What is the actual yield of barium chloride ? grams

Answer:

  • Theoretical yield = 568.47 g BaCl₂
  • Actual yield = 406.45 g BaCl₂

Explanation:

Hydrochloric acid(aq) + Barium hydroxide(aq) → Barium chloride(aq) + Water(l)

  • 2HCl(aq) + Ba(OH)₂(aq) → BaCl₂(aq) + 2H₂O(l)

For the theoretical yield of BaCl₂ we use all the initial mass of HCl, and convert it into mass of BaCl₂:

  • 5.46 g HCl * [tex]\frac{1molBaCl_{2}}{2molHCl} *\frac{208.23g}{1molBaCl_{2}} =[/tex] 568.47 g BaCl₂

For the actual yield we multiply the theoretical yield by the percent yield:

  • 568.47 g BaCl₂ * 71.5/100 = 406.45 g BaCl₂
