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. C6H6O6 + 2 H+ + 2 e– → […]
