6-B. Vitamin C (ascorbic acid) from foods can be measured by titration with 13: CH4O6 + + H2O = C,H,O + 30 + 2H Ascorbic acid Triiodide Dehydroascorbic acid FM 176.126 Starch is used as an indicator in the reaction. The end point is marked by the appearance of a deep blue starch-iodine complex when unreacted 15 is present. (a) If 29.41 mL of Iz solution are required...

Titration of an Antacid (i.e., an anti-acid, in other words a base) Part A Procedure: 1. To a beaker of appropriate size add 190 mL of distilled water. Afterwards, using your 10 mL graduated cylinder, add 10 mL of 4 M HCl (hydrochloric acid) stock solution (CAUTION - STRONG ACID-CORROSIVE!) to the 190 mL of distilled water. Mix the solution well. Using a Rainin pipet, carefully pipet 10.000...
