Question 27 A 0.1220 g vitamin C tablet was dissolved in acid. This required 11.50 mL of 0.01740 M KIO3 to reach the endpoint. Considering these two half-reactions, KIO3 +5 KI + 6H*→ 312 +6K++ 3H₂O C6H806+ 12→ C6H606+21+ 2H* Calculate percent by weight of ascorbic acid in the tablet. 86.66 % 74.42% O 58.39 % 64.31%
