4.95 The amount of ascorbic acid (vitamin C; C,H¿O) in tablets is determined by reaction with bromine and then titration of the hydrobromic acid with standard base: CH,O(aq) + Br,(aq) → C,H,O,(aq) + 2HBr(aq) HBr(aq) + NaOH(aq) → NaBr(aq) + H,O(1) A certain tablet is advertised as containing 500 mg of vitamin C. One tablet was dissolved in water and reacted with Br,. The solu- tion was then titrated with 43.20 mL of 0.1350 M NaOH. Did the tablet contain the advertised quantity of vitamin C?

A chemistry student needs to standardize a fresh solution of sodium hydroxide. He carefully weighs out 283. mg of oxalic acid (H,C,04), 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 70.8 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. M x10
