Explanation:
- A homogeneous mixture is defined as the mixture in which solute particles are evenly distributed into a solvent.
For example, iced tea with no ice is a homogeneous mixture.
Also, a cheddar cheese contains even distribution of solute particles. Hence, it is also a homogeneous mixture.
- On the other hand, a mixture in which solute particles are unevenly distributed in a solvent is known as a heterogeneous mixture.
For example, both rocky road ice cream and trail mix are heterogeneous mixture.
