Question

3. Experimental Pro perimental Procedure, Part B.1. What is the purpose of adding NaHCO, to th balanced equation for its reaction. Iding NaHCO, to the reaction mixture? Explain. Write a Experimental Procedure, Part C. What is the oxidizins arent in the titration? b. What is the color change of the starch indicator that signals the stoichiometric point in 5a. Eight ounces (1 fl. oz = 29.57 mL) of orange juice contains 160% of the recommended daily allowance of vitamin (RDA = 75-90 mg for adults). How many milliliters of the orange juice will provide 100% of the recommended daily allowance? b. Assuming 80 mg of vitamin C present in 29.57 mL of the orange juice, how many milliliters of 0.0102 M KIO would be required to reach the stoichiometric point?

Answer 1

SOLN 3

Experimental proceure is not giving so I am giving generic solution

The sodium bicarbonate is a mild base which when added to react with acid , and hence remove the acid from the reaction mixture. Bicarbonates react with acids and remove them by releasing carbon dioxide
