A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weighs out 400. mg of oxalic acid (H,C204), 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.
