Experiment: Synthesis of Potassium Permanganate

Objective:

To demonstrate the synthesis of potassium permanganate, an important inorganic chemical with various industrial applications.

Materials:


  • Potassium hydroxide (KOH)
  • Manganese dioxide (MnO2)
  • Sodium chlorate (NaClO3)
  • Water (H2O)
  • Glassware: beakers, Erlenmeyer flask, condenser, thermometer, stirring rod

Procedure:


  1. In a fume hood, dissolve 50 grams of KOH in 100 mL of water in a 500 mL beaker.
  2. Add 100 grams of MnO2 and stir until a homogeneous mixture is obtained.
  3. Dissolve 50 grams of NaClO3 in 100 mL of water in a separate beaker.
  4. Slowly add the NaClO3 solution to the KOH-MnO2 mixture, while stirring continuously.
  5. Attach a condenser to the Erlenmeyer flask and heat the mixture to 90-95 °C for 30 minutes.
  6. Cool the mixture to room temperature and filter it to remove any unreacted solids.
  7. Concentrate the filtrate by evaporation until crystals of potassium permanganate start to form.
  8. Filter the crystals, wash them with cold water, and dry them in an oven at 110 °C.

Key Procedures:


  • The reaction between KOH, MnO2, and NaClO3 forms potassium permanganate (KMnO4).
  • Heating the mixture to 90-95 °C accelerates the reaction and promotes the formation of KMnO4.
  • Crystallization by evaporation allows the isolation of KMnO4 from the reaction mixture.

Significance:


  • Potassium permanganate is a powerful oxidizing agent with a wide range of applications.
  • It is used in water treatment, as a disinfectant, and as a bleaching agent in the textile industry.
  • In the chemical industry, KMnO4 is employed in the production of other chemicals, such as potassium dichromate and manganese dioxide.
