You are given solutions of hydrochloric acid and sodium hydroxide and must determine their concentrations. You use 27.52 mL of NaOH to titrate 100.00 mL of HCl and 18.45 mL of sodium hydroxide to titrate 50.00 mL of 0.0782 M sulfuric acid. Determine the unknown concentrations of the hydrochloric acid and the sodium hydroxide.
