Question
If the titration of a 25.0 mL sample of calcium hydroxide requires 34.45 mL of 0.100 M perchloric acid, what is the molarity of the base?
2 HClO4(aq) + Ca(OH)2(aq) → Ca(ClO4)2(aq) + 2 H2O(l)
2 HClO4(aq) + Ca(OH)2(aq) → Ca(ClO4)2(aq) + 2 H2O(l)

By definition, M Ca(OH)2 = mols/L solution.
mols HClO4 = M x L = ?
mols NaOH = 1/2 that (from the coefficients in the balanced equation).
Then M Ca(OH)2 = mols Ca(OH)2/L Ca(OH)2.
mols HClO4 = M x L = ?
mols NaOH = 1/2 that (from the coefficients in the balanced equation).
Then M Ca(OH)2 = mols Ca(OH)2/L Ca(OH)2.
