1. We want to measure the amount of chemical A in a blood sample using chemical, C where A + C → D. For a 50.0 mL sample of blood, it takes 23.2 mL of a 0.010 M solution of C to reach the equivalence point. Under normal circumstances, the concentration of A should be 0.005 M. What can we determine?

2. 12.0 mL of 1.00 M base NaOH has been added to 5.0 mL of 2.00 M HCl. They react as: HCl + NaOH → NaCl + H2O. Which of the following statements is true?
