O Chemical Reactions Standardizing a base solution by titration 3/5 Bis A chemistry student needs to standardize a fresh solution of sodium hydroxide. He carefully weighs out 36. 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 his sodium hydroxide solution. When the titration reaches the equivalence point, the student finds he has used 35.1 mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution. Round your answer to 2 significant digits. Ом OP G
