Question: 1 / 400

What is a stable physical mixture of two or more substances?

Emulsions

A stable physical mixture of two or more substances is referred to as an emulsion. Emulsions consist of two immiscible liquids - typically oil and water - stabilized with an emulsifying agent to prevent the components from separating. This is the correct answer because emulsions are known for their stability over time compared to other types of mixtures like solutions, salts, or suspensions.

In the context of the other options:

- Salts are not a physical mixture of substances but rather a chemical compound composed of positively and negatively charged ions.

- Solutions involve the dissolution of one substance (solute) into another (solvent) at a molecular level, resulting in a homogeneous mixture.

- Suspensions are mixtures in which particles are dispersed in a liquid but tend to settle out over time due to gravity.
