Separation Of Mixture Of a Solid And a Liquids
All the mixtures mixtures containing a solid and a liquid are separated by one of the following processes :
(i) By filtration (iv) By crystallisation
(ii) By centrifugation (v) By chromatography
(iii) By keeping three layers of filter paper on one side and one layer on the other side)[see Figure 60(d)].
(iv) This cone of filter paper is placed inside a funnel [as shown in Figure 60(e)].It is then used for the process of filtration in a science laboratory.
Keeping these points in mind,we will now describe filtration as a method for separating mixtures.
