When a Vitamin C (ascorbic acid; MM = 176.12 g mol-1) tablet is crushed, dissolved and titrated with 0.0340 M KIO3(aq) to a purple/blue endpoint (given by a starch indicator), the volume of KIO3 used is 29.80 mL. If 60 mg of ascorbic acid is the recommended dietary allowance (i.e., 100% of the RDA), then what is the % RDA for the Vitamin C in the tablet? KIO3(aq) + 5 KI + 6 H+ → 3 I2(aq) + 3 H2O I2 (aq) + ascorbic acid → 2 I- + dehydroascorbic acid

The mixture contains benzoic acid, 2-napthol, and naphthalene. Dissolve the mixture in the polar solvent ether. When you react the mixture with 10% NaHCO3(sodium bicarbonatea weak base in aqueous solution) reacts with benzoic acid and forms sodium benzoate an ionic compound (similar to NaCl) that dissolves in aqueous solution (heavier than ether in density) and goes to the bottom of the centrifuge tube or to the bottom of the separatory funnel forming two layers. Then remove the bottom aqueous layer and collect in a beaker labeled as bicarbonate extract. Acidify the bicarbonate extract in the beaker to give benzoic acid. The top ethereal layer contains in the centrifuge tube or separatory funnel 2-napthol and naphthalene. To this top layer add 10% NaOH (sodium hydroxideis a strong base in aqueous solution reacts with only 2-napthol, a weak acid forming 2-napthoxide an ionic compound soluble in aqueous solution (similar to NaCl) that goes to the bottom of the centrifuge tube or to…
