In Lab 9, students performed acid-base titrations. Redox
reactions can also be used in titrations. An example is the
titration of ascorbic acid
(H2C6H6O6) in lemon
juice using triiodide (I3− ). A starch
indicator will turn the solution blue-black at the endpoint. The
half-reactions involved are shown below.

please help with this question.
Extra credit Homework on Acid-Base Titration You can use the technique of titration to determine the concentration of a mixture of sodium carbonate and sodium bicarbonate. Titration is performed using a solution with a known concentration of hydrochloric acid (HCI). During the titration, HCl reduces gradually the alkalinity of the solution until the pH is acid. The reaction occurs in two stages in the first part you titrate the total amount of carbonates present in...
