Solution Stoichiometry

We have already explored gravimetric stoichiometry (mass-to-mass) However, most industrial reactions take place in solution –Easier to manipulate and control –Many chemical reactions only occur if the reactants are in solution Solution stoichiometry (or volumetric stoichiometry) is a method of calculating the concentration of substances in solution

Steps to Solving Solution Stoichiometry Problems 1.Write the balanced chemical equation 2.Set up a stoich table OR 1.Write the balanced chemical equation 2.Convert given values to moles 3.Use the mole ratio to solve for unknowns

Example: A mL sample of sulfuric acid reacts completely with 15.9 mL of a mol/L potassium hydroxide solution. Calculate the molar concentration of the sulfuric acid. H 2 SO 4(aq) + 2 KOH (aq)  2 H 2 O (l) + K 2 SO 4(aq) C = X mol L = mol/L mol/L n = X mol KOH X 1 mol H2SO4 2 mol KOH = X mol H2SO4 = mol X L 1 L = X mol V L L
