Filtration is a useful technique for separating solids from liquids or gases. It is commonly used when there is a mixture where one component is a solid and the other is a liquid or a gas. By using a filter, it is possible to physically separate the solid particles from the liquid or gas.
To perform filtration, you will need the following materials:
1. Filter paper or a filter funnel: This is a porous material that allows the liquid or gas to pass through while retaining the solid particles.
2. Filtration apparatus: This typically includes a flask or a funnel with a filter paper supported by a filtration flask or cone that collects the liquid or gas that passes through the filter.
3. Mixture to be filtered: This is the mixture containing the solid particles and the liquid or gas.
To carry out the filtration process:
1. Set up the filtration apparatus by placing the filter paper in the funnel or the filter funnel in the filtration flask.
2. Place a clean container (such as a beaker or flask) below the filter to collect the filtrate (the liquid or gas that passes through the filter).
3. Pour the mixture into the funnel or filter funnel, making sure that the solid particles are retained by the filter paper while the liquid or gas passes through.
4. Allow the liquid or gas to flow through the filter, collecting it in the container below. The solid particles will be left on the filter paper.
5. Once the filtration is complete, carefully remove the filter paper containing the solid particles and dispose of it properly.
6. The collected liquid or gas in the container is now the filtrate, which is separated from the solid particles.
Filtration is commonly used in various applications such as in laboratories, industrial processes, and even in everyday situations. It is an effective method for separating solids from liquids or gases based on size and can help obtain purified substances or remove impurities from mixtures.
