* Heterogeneous Mixture: A heterogeneous mixture is a mixture where the components are not evenly distributed throughout. You can visually distinguish the different parts.
* Filtration: Filtration separates a solid from a liquid or gas by passing the mixture through a filter. The solid particles (the residue) are trapped by the filter, while the liquid or gas (the filtrate) passes through.
Example:
Imagine filtering sand and water. The sand particles (residue) are trapped by the filter paper, while the water (filtrate) passes through. You can clearly see the sand particles as a separate component from the water, making it a heterogeneous mixture.
Important Note: While the residue is generally heterogeneous, it can sometimes be a homogeneous mixture if the solid is completely dissolved in the liquid. However, in most practical filtration scenarios, the residue will be a heterogeneous mixture.
