Suppose 50.0 mL of an aqueous solution containing an unknown monoprotic weak
acid is titrated with 0.250 M KOH. The titration requires 31.52 mL of the potassium hydroxide
solution to reach the equivalence point. What is the concentration (in molarity) of the unknown
HA + KOH --> H2O + KA
mols KOH = M x L = ?
mols HA = moles KOH (from the coefficients in the balanced equation.
M HA = moles HA/L HA
