Solution
Mixtures:
When two or more substances mix with each other without participating in a chemical change, the resulting substance is called a mixture. Mixtures are made up of two or more substances that are not chemically combined with each other.
The properties of mixtures are:
The components of a mixture can be easily separated.
The proportion of the components is variable.
Some common examples of mixtures: are crude oil, seawater, air, ink, and gunpowder.
The solid-liquid mixture in which the solid is insoluble can be separated by the filtration method.
Method of separation:
Filtration:
It is the separation method used to separate the undissolved solid component of a solid-liquid mixture using a filter medium that allows the liquid to pass through it and the solid part being remained on the filter medium thus used.
Filtrate:
The liquid which gets passed from the filter medium used such as filter paper is called the filtrate.
Residue:
It is the solid part of the mixture that remains on the filter medium such as the filter paper.
Given is a figure elaborating the filtration process.
A filter paper is made into a cone and placed in a funnel. The solid particles remain behind on the filter paper while the liquid collects below.
