You are performing a titration experiment using a standard solution of 0.15M KOH and 15mL of an acid. You do not know the concentration or the identity of the acid, but it was neutralized by exactly 15mL of KOH. Using titration calculations, can you calculate the concentration of this acid? Explain why or why not.
