To determine the concentration of a solution of perchloric acid, a 75.00-mL sample is placed in a flask and titrated with a 0.1274 M solution of barium hydroxide. A volume of 33.58 mL is required to reach the phenolphthalein endpoint. Calculate the concentration of perchloric acid in the original sample.
The main objective of performing a titration experiment is to calculate the molar concentration of your known sample by letting react to a known titrant with an established concentration. The chemical reaction of the titrant and your sample must be established for the calculation.
Answer and Explanation: 1
The balanced chemical equation for perchloric acid and barium hydroxide is:
