Several different methods can be used to separate mixtures, and the method chosen depends on the nature of the mixture to be separated. To separate a mixture of an insoluble substance from a liquid, you need a container with a hole in the bottom, filtration material such as charcoal or gravel, and a larger container to capture the liquid.Know More
Identify the nature of the substances in the mixture you wish to separate. If your mixture contains insoluble particles such as dirt in a liquid such as water, filtration must be used to separate the two.
For filtration, you need a container with a hole in the bottom, filtration material such as charcoal, gravel or sand and a larger container to catch the liquid that remains from the filtration process.
Layer the bottom of the container with a hole with your filtration material of choice. Charcoal, sand or gravel are all good choices for separating dirt from water. Place this container in the larger container.
Pour the mixture of dirty water into the container with the filtration material. The filtration material catches the large particles of dirt and allows the water to seep through the hole into the larger container.
To separate sugar from its mixture with sand, a proportionally large amount of water is added to the mixture and shaken vigorously to allow the sugar to dissolve. The solid-liquid mixture is filtered using a porous material to retain the sand on the filter and to allow the liquid portion to pass through. The liquid contains the sugar originally present in the solid mixture.Full Answer >
