1. One method used commercially to peel potatoes is to soak them in a solution of NaOH for a short time, remove them from the NaOH, and spray off the peel. The NaOH is analyzed periodically. In one such analysis, 45.7 mL of 0.500 M H2SO4 is required to react completely with a 20.0 mL sample of the NaOH solution. The reaction involved is:
2 NaOH + H2SO4 —–→ Na2SO4 + 2 H2O _________a. How many moles of H2SO4 was used in the analysis? (4 pts)
________b. Based on the equation, how is NaOH stoichiometrically equivalent to H2SO4? (2 pts)
________c. How many moles of NaOH is present in the solution? (4 pts)
________d. What is the molarity of the NaOH solution? (4 pts)
