||| O CHEMICAL REACTIONS Standardizing a base solution by titration A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weighs out 248. mg of oxalic acid (H₂C₂O), 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 68.0 ml. of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution. Round your answer to 3 significant digits. X 1 5
