Transcribed Image Text: Standardizing a base solution by titration
A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weighs out 230. mg of oxalic acid (H,C,0), 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 109.3 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.
