The liquid passes through the filter paper and collect in the beaker kept below the funnel. At water treatment works, the river water or lake water is filtered by using sand filters. Allow the mixture of sand and water to stand undisturbed for some time. There are some mixtures which contain insoluble solid particles suspended in a liquid. The clear water is then decanted into another beaker. <> Sedimentation is the process of the heavier component in a mixture settling down after adding water to it. Ways to bring change in an object / material. The used tea leaves are separated from prepared tea by the method of filtration.

The holes of filter paper are so small that they cannot be seen with naked eyes. The deposition of sand at the bottom of a beaker is called sedimentation. endobj A mixture of chalk and water is separated by filtration. Question 3 How will you separate a mixture of sand and water? A mixture of insoluble solid in a liquid is separated into the solid and clear liquid. Sometimes the water fetched from a river, lake or pond is muddy due to the presence of fine clay particles suspended in it. The solid particles do not pass through the filter paper and remain behind on the filter paper. To further remove dust, use filtration. However, filtration using vacuum technology could be fast. Loading is the process in which alum particles are deposited on suspended clay particles of muddy water to make them heavy and settle down rapidly. To further remove dust, use filtration. DIFFERENCE BETWEEN FILTRATION AND DECANTATION Filtration is the direct separation of the entire solution through a filter, where the solid is trapped on the filter and the liquid passes through. Sugar dissolves in water so the mixture of sugar and water cannot be separated by method of decantation. When a long-ripened wine is to be served, sommeliers and experts recommend decanting the liqueur before serving it. It contains sand particles scattered throughout water. Question 7 How will you separate a mixture of oil and water? A mixture of sand and water contains sand particles suspended in water.

The solid matter which settles down at the bottom of a liquid is called a sediment. On keeping ,the heavier sand particles will settle down at the bottom of the beaker. Decantation is also used to separate liquids that don’t mix with each other. The piece of alum is then put in the beaker of muddy water and rotated in it three or four times by holding from thread. Example – Decantation helps a little in removing the tea leaves but filtration helps further.

( Log Out /  Question 9 Define the term filter paper, residue and filtrate? When we add water to rice or pulses taken in a vessel , then the impurities such as dust and soil particles get separated and go into water. In this way the suspended clay particles become loaded with heavy alum particles. Due to this the water becomes a little dirty. Filtration is used for separating insoluble substances from a liquid. Question 4 What substance is used for loading the clay particles suspended in muddy water? After sedimentation , we get two layers. Students: work in teams to observe different materials being mixed together record their observations in a table and discuss them draw annotated diagrams of the separation technique (Decantation) Lesson… After this piece of alum is taken out from the beaker. Question 11 How will you separate a mixture of sand and water? Sand can be separated from sand water mixture by the method of decantation. Fruit juice is also filtered by using a strainer as filter to remove the seeds and solid particles of pulp. The major difference between decantation and filtration is in the process by which it is achieved. In everyday life different kinds of filters are used for example a wire mesh ,a piece of cotton,  a piece of muslin cloth , tea-strainer. The solid which remains on the filter paper is called residue. Question 12 Explain the process by which tea leaves are separated from prepared tea?
