Question:

(a) A 0.1044-g sample of an unknown monoprotic acid requires 22.10 mL of 0.0500 M NaOH to reach the end point. What is the molecular weight of the unknown?

(b) As the acid is titrated, the pH of the solution after the addition of 11.05 mL of the base is 4.89.What is the K_a for the acid?

(c) Using Appendix D, suggest the identity of the acid. Do both the molecular weight and K_a value agree with your choice?
