How could you have used the color change property of iron(III) chloride to monitor when the reaction had reached completion? You could have added drops of iron(III) chloride directly to the reaction mixture until a change in color occurred. You could have placed a drop of iron(III) chloride directly to the reaction mixture and waited until the color disappeared. You could have placed a drop of reaction mixture every minute in one test tube containing iron(III) chloride until there was no color change. You could have placed a drop of reaction mixture into different test tubes containing iron(III) chloride every minute until there was no color change. Incorrect
