Find the odd one out : solutions, compounds, suspensions, emulsions

Explanation

To find the odd one out among the options: solutions, compounds, suspensions, and emulsions, we can analyze each term:

1. **Solutions**: A solution is a homogeneous mixture where a solute is dissolved in a solvent. The components are mixed physically and cannot be separated by filtration.

2. **Compounds**: A compound is a substance formed when two or more elements are chemically bonded together. This means that compounds are not mixtures; they have a fixed composition and specific properties.

3. **Suspensions**: A suspension is a heterogeneous mixture where solid particles are dispersed in a liquid. The solid particles can settle out over time and can be separated by filtration.
