Ba(aq)^(2+) + 2 OH(aq) ^(-) + 2 H(aq) ^(+) + SO4 (aq)^(2-) = BaSO4 (s) + 2 H20 (Reaction 1) equivalence volume: 0.3582 concentration of the acid: 0.020547 Elaborate, please Concentration of Ba(OH)2 by titration: Use the equivalence volume and concentration of the acid to calculate the number of moles of acid added. Then calculate the moles of Ba(OH)2 present in the original sample based on the stoichiometry in Reaction 1. Finally, calculate the concentration of Ba(OH)2 in the original sample.
