1) You are given solutions of HCl and NaOH and must determine their concentrations. You use 37.0mL of NaOH to titrate 100mL of HCl and 13.6 mL of NaOH to titrate 50.0mL of 0.0782 M H2SO4. Find the unknown concentrations.
Molarity of NaOH and molarity of HCL?

2) Sodium hydroxide is used extensively in acid-base titrations because it is a strong, inexpensive base. A sodium hydroxide solution was standardized by titrating 28.00mL of 0.1598 M standard HCl. The initial buret reading of the sodium hydroxide was 2.54mL, and the final reading was 39.85mL. What is the molarity of the base solution?
