1.why is potassium permanganate used in the process of distillation of water?
Potassium permanaganate is used to purify water, especially stop organic growth in water stills that are permanantly set up. If a water still is set up for a one time distillation of water then the KMnO4 is not really needed. In the case of a still that is set up permanently, yet used intermittantly it is wise to add something that stops organic growth as the water in the still will turn green and may 'bump' more during distillation. There is a hazard over time to the technician who may come to take the still apart for cleaning from possible legionaires disease (see (Broken Link Removed)
Potassium permanganate is commonly used in the process of distillation of water for its oxidizing properties and ability to remove impurities. It serves several important purposes:
1. Sterilization: Potassium permanganate helps disinfect the water by killing or inactivating microorganisms present. It is particularly effective against bacteria, viruses, and parasites.
2. Removal of organics: Potassium permanganate aids in the oxidation of organic compounds present in water, such as algae, bacteria, and other decomposed materials. This process helps to remove unpleasant odors and tastes caused by these substances.
To use potassium permanganate in the distillation process, follow these steps:
1. Dissolving: Start by dissolving a small amount (around 1 gram per liter) of potassium permanganate crystals in a container of water. Stir until completely dissolved. The solution should turn pink or purple.
2. Addition to the distillation apparatus: Once the distillation apparatus is set up, carefully add the potassium permanganate solution to the water that will be distilled. The concentration of potassium permanganate should be low enough not to affect the distilled water's taste or color.
3. Distillation process: Proceed with the distillation process as normal, taking care that the water passes through the potassium permanganate solution. This ensures that any microorganisms and organic impurities present in the water are oxidized and removed.
It's important to note that while potassium permanganate is effective in sterilizing and removing organic impurities, it should be used in moderation to avoid excess residues in the distilled water. Proper handling and dosage should be followed to ensure safe and effective use.
