Experiment: Synthesis of Potassium Permanganate
Objective:
To synthesize potassium permanganate (KMnO4), a widely used oxidizing agent in various industrial processes.Materials:
- Manganese dioxide (MnO2)- Potassium hydroxide (KOH)
- Sodium hydroxide (NaOH)
- Water
- Glassware (beakers, pipettes)
- Heat source (Bunsen burner)
Procedure:
- Dissolve 20 g of KOH and 10 g of NaOH in 100 ml of water in a beaker.
- Add 15 g of MnO2 to the solution and stir continuously.
- Heat the mixture to a gentle boil and maintain for 1 hour, stirring occasionally.
- Filter the hot solution through a Buchner funnel to remove unreacted MnO2.
- Transfer the filtrate to a large beaker and cool it to room temperature.
- Add 250 ml of ice water to the beaker and stir vigorously.
- Crystallization of KMnO4 will occur. Filter the crystals through a Buchner funnel.
- Wash the crystals with cold water and dry them in an oven at 100°C.
Key Procedures:
- Oxidation: MnO2 is oxidized to MnO4- by the strong oxidizing agent hydroxide ions (OH-).- Crystallization: The decrease in temperature and the addition of ice water promote the precipitation of KMnO4 crystals.
- Filtration: The crystals are separated from the mother liquor by vacuum filtration.
Significance:
- Potassium permanganate is a versatile oxidizing agent used in:- Industrial bleach and disinfectant
- Water purification and wastewater treatment
- Chemical synthesis
- The experiment demonstrates the principles of oxidation, precipitation, and crystallization in inorganic chemistry.
