Filtration is the method of separation used for separating an insoluble solid from a liquid using a filter. During filtration, the insoluble solid particles retained in the filter, and the liquid passes through it.

Match the following. Column A Column B 1. Filtration a. Soluble impurity 2. Chlorination b. Sedimentation 3. Common salt c. Chlorine tablets 4. Insoluble impurities d. Loading 5. Alum e. Filter paper

1 - e Filtration is the process of separating insoluble impurities from liquid. Filter paper is used in the process of filtration. 2 - c Chorine tablets are used in the chlorination process. It kills germs and makes the water fit for drinking. 3 - a Common salt dissolves in water; it is a soluble impurity. We can remove soluble impurities by evaporation or distillation method. 4 - b Insoluble impurities are removed through sedimentation process. It can be removed by the filtration method also. 5 - d The rate of sedimentation process can be improved by adding special chemicals such as alum. This process is called loading. It helps to remove impurities from water. Column A Column B 1. Filtration e. Filter paper 2. Chlorination c. Chlorine tablets 3. Common salt a. Soluble impurity 4. Insoluble impurities b. Sedimentation 5. Alum d. Loading
