impurities. Boiling - Boiling is the best and simplest method to purify water. After straining the water twice through clean muslin cloth‚ it is boiled for ten minutes lo kill the microbes present in it and also remove the temporary hardness of water. Filtration - Different varieties of filters are used to purify the water at domestic level. Filter rods can be installed. These rods are made of china porcelain and it is porous and hollow from the centre. When water is put through it‚ it is purifies and drips

dissolve. Therefore‚ when selecting a solvent it is important that it does not cause a chemical or flammable reaction to the substance. Then‚ we continue with the process until the solution is ready to be filtered using the Buchner funnel. During filtration the pure substance will completely separate from the impure substances completing our experiment. Procedures As stated above‚ first choose a solvent‚ for this particular experiment we will be using solvent H2O. using a hot plate bring to a boil
