To determine sulfate ions in medicinal substances, a barium chloride solution is used. determine the mass of barium sulfate. Which is obtained by the interaction of 20 g of barium chloride with sulfuric acid.

BaCl2 + H2SO4 = BaSO4 + 2HCl
n (BaCl2) = m \ M = 20 \ 208 = 0.096 mol
for n (BaCl2) = n (BaSO4) = 0.096 mol
m (BaSO4) = nM = 0.096 * 233 = 22.368 g
Answer: 22.368 g
