The amount of ascorbic acid (vitamin C, C&HgO6) in tablets is determined by reaction with bromine and then titration of the hydrobromic acid with standard base C6H8O6 + Br2 -> C,H6O6 + 2HBR HBr + NAOH -> NaBr + H2O A certain tablet is advertised as containing 500 milligrams of vitamin C. A single tablet is dissolved in water and reacted with Br2, followed by titration with 43.20 mL of 0.1350 M NAOH. Verify if the tablet contained the advertised quantity of vitamin C.
