Calculate the volume of 0.10M NaOH required to neutralize (a) 10mL of 0.10M HCl (b) 10mL of 0.10M acetic acid (CH3COOH) and (c) 10mL of 0.10M H3PO4, a triprotic acid.
A student weighs a sample of potassium hydrogen phthalate (KHP) to prepare a primary standard for a titration. She later discovers that the KHP was contaminated with sugar. To determine the amount of KHP in the mixture, she takes 5.942 g of the mixture and make a 100.0 mL solution. The student then titrates 10.00 mL of this solution with a 0.1491 M sodium hydroxide solution. She finds that 13.12 mL of the NaOH solution is needed to reach the...

If 9.77 mL of an acetic Acid solution required 10.71 mL of 1.0785 M NaOH to reach the endpoint, what's the concentration of the Acetic Acid solution?
Constant-boiling HCl can be used as a primary standard for acid-base titrations. A 50.00 mL sample of constant-boiling HCl with a concentration of 0.1225 M was collected and titrated to an end point with 35.60 mL of Ba(OH)2 solution. What is the molarity of the Ba(OH)2 solution?
