1. It took 45.05 mL of NaOH to titrate 50.00 mL of 0.1080 M HCl. Calculate the molarity of the NaOH solution.
2. It took 37.50 Ml of NaOH to titrate 0.9061 g of primary standard KHP (FW 204.23). Calculate the molartiy of the NaOH solution.
3. Give examples of:
a. Monoprotic weak acid
b. Diprotic weak acid
c. Triprotic weak acid
To determine the molecular weight of a newly synthesized triprotic acid, a student dissolved a pure sample (400.0 mg) of the triprotic acid in water to a total volume of 100.0 mL. The student then took a 25.00 mL aliquot of this solution and titrated it with 15.90 mL of 0.0750 M NaOH to reach the second end point. The molecular weight of the acid (in g/mol) is:
A 0.210-g sample of an acid (molar mass = 192 g/mol) is titrated with 30.5 mL of 0.108 M NaOH to a phenolphthalein endpoint. Is the acid monoprotic, diprotic, or triprotic?
