If 35.23 mL of 0.250 M aqueous sodium hydroxide is required to titrate a 50.0 mL sample of hydrochloric acid, calculate the concentration of the hydrochloric acid.
Potassium acid phthalate reacts with sodium hydroxide to form potassium sodium phthalate. A 0.2500 g sample of potassium acid phthalate requires 25.45 mL of a standard sodium hydroxide solution to react completely. Calculate the concentration of this solution to 3 significant figures.
Potassium hydroxide reacts with dilute aqueous phosphoric acid to produce potassium hydrogen phosphate. Calculate the volume of a 0.1500 M solution of potassium hydroxide needed to titrate 40.00 mL of 0.06560 M aqueous phosphoric acid.
