A chemist had a bottle of HCl (aq) of unknown concentration. She performed a titration experiment in order to determine its concentration. She pipeted 25.00 mL of the HCl solution into an Erlenmeyer flask. She then added about 21 mL of deionized water and 3 drops of phenolphthalein indicator dye to the flask. She titrated this mixture with 0.09063 M NaOH (aq), and obtained a permanent, pale pink endpoint after the addition of 36.68 mL of NaOH (aq). Given that...

A 25.0 mL NaOH solution of unknown concentration was titrated with a 0.189 M HCl solution. 19.6 mL HCl was required to reach equivalence point. In a separate titration, a 10.0 mL H3PO4 solution was titrated with the same NaOH solution. This time, 34.9 mL NaOH was required to reach the equivalence point. What is the concentration of the H3PO4 solution?

A solution of HCl has an unknown concentration. 10.00 mL of the HCl solution was measured and several drops of phenolphthalein were added. The solution remained colorless. A quantity of 84.51 mL of 1.000 M NaOH was added before a pink color persisted in the solution. What was the concentration of the HCl solution?
