Chemical Filtration

The video tutorial demonstrates a practical experiment to remove toxic chemicals from water using potassium permanganate and activated charcoal. Initially, water is contaminated with potassium permanganate, turning it purple. An attempt to filter the water using only filter paper fails, as the chemical is highly soluble. Activated charcoal is then added, which bonds with the chemical and allows it to be filtered out, resulting in purified water. This method is used in public water supplies and aquatic systems to ensure safety and maintain environments.
