Redox titration

HOW TO CARRY OUT THE TITRATION?


This method requires:
  • Adapted material: (burette, magnetic stirrer, magnetic stir bar, reagents prepared according to the pharmacopoeia standards, graduated pipettes).
  • Personal and collective adapted protective equipment (laboratory coat, glasses).
 
Equipment and reagents:
  • Burette
  • Magnetic stirrer
  • 250 mL Erlenmeyer flask
  • Weighing cup
  • Tittered iodine solution
  • Magnetic stir bar
Experimental procedure:
Dissolve approximately 40 mg precisely weighed in a 10 mL mix of diluted sulfuric acid (10% v/v) and 80 mL CO2 free water (previously brought to a boil). Titrate with a 0.025M iodine solution until the reaction medium turns yellow.
