WebThis was followed by the addition of excess KI producing I2 and CuI precipitate from Cu 2+ (Reaction 1). Then, the liberated I2 reacted with the excess KI forming triiodide anion (Reaction 2), which was then titrated with Na 2 S 2 O 3 titrant (Reaction 3). This entire solution required 17.60 mL of the titrant to reach the starch end point.
