Lab Report

Acid-Base Dependence of a Redox Reaction

Introduction: Redox reactions is when the oxidation state of one reactant decreases and the oxidation state of another increases.   This experiment using permanganate and ferrocyanide ion shows how the acid base characteristics of the reacted solution can exert

Purpose:   The purpose of this lab is to investigate the reaction that occurs between the permanganate ion and ferrocyanide. In this experiment, titration will be used in order to observe the amounts of solutions needed to form a reaction.

Procedure: 100mL supply of 0.01M potassium permanganate as well as a 100mL supply of 0.02M ferrocyanide was obtained.   Once they were obtained, a clean buret was filled to the top with the permanganate solution. Then with a pipet, 25 mL of the ferrocyanide solution was put into a 250mL flask. Then 40mL of 3M H2SO4 and 80mL of deionized water was added into the flask.   Then we began to titrate the ferrocyanide with the permanganate slowly, while constantly swirling the flask. The end point was reached when reddish-orange color appeared. We then repeated the steps again for a second trial.
Then 50 mL of deionized water was obtained in a 125mL flask. We then added 0.25 grams of ammonium sulfate as well as 25mL of ferrocyanide. We then refilled the buret with the permanganate solution and began to titrate in 5mL increments for 15mL and then began to titrate with drops while constantly swirling.   We allowed the solution to settle. We reached an endpoint when the solution became a faint reddish color. We then repeated the steps again for a second trial.   Finally, the permanganate was titrated with the ferrocyanide solution. Using a clean buret, we filled it with ferrocyanide.   Then 50 mL of 1.2M NaOH solution was added into a 125mL flask, as well as 25mL of permanganate solution.   Using the buret, we added 1-2mL of ferrocyanide into the flask. We then added...
