A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weighs out 233. mg of oxalic acid (H₂C₂O4), a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250. mL of distilled water. The student then titrates the oxalic acid solution with her sodium hydroxide solution. When the titration reaches the equivalence point, the student finds she has used 63.2 mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution. Be sure your answer has the correct number of significant digits.

20. Consider the following hypothetical acid-base titration where A represents the acid and B represents the base. The products of this reaction are salt and water. Assume the equation is balanced as written. 3A + 2B --> salt + water (OR 3 A + 2 B right arrow salt + water) Two burets are setup with one containing acid, A, and the other containing base, B. The initial volume of buret A is 1.32 mL and the initial volume of buret B is 1.14 mL. Acid from buret A is added to a flask until the final volume of buret A is 12.10 mL. Base from buret B is added to the flask until the titration reaches the endpoint. The final volume of buret B reads 24.96 mL. Calculate the molarity of the acid, A, if the base has a molarity of 1.213 molar. You may want to create a data table to help you organize your work. Do not type units with your answer.
