Question

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 1

• Theoretical yield = 568.47 g BaCl₂

• Actual yield = 406.45 g BaCl₂

Step-by-step 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 *
  `(1molBaCl_(2))/(2molHCl) *(208.23g)/(1molBaCl_(2)) =` 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
