We will obtain clear water from a sample of muddy water by the process of filtration. A filter paper is one that has very fine pores in it. Figure 5.12(a, b) shows the steps involved in using a filter paper. A filter paper folded in the form of a cone is fixed in a funnel. The mixture is then poured on the filter paper. The mud stays on the filter paper and clean water paper is obtained in the beaker.
