Question

Is mouthwash an element, a compound, a homogeneous mixture, or a heterogeneous mixture?

Answer 1

An element is a substance that can not be broken down in simpler substances by chemical means. A compound is a substance that contains two or more substances that are chemically combined in a definite and fixed proportion by mass. A mixture is a combination of two or more substances which are not chemically combined. Mouthwash is an example of homogeneous mixture.

Answer 2

Answer: Option (c) is the correct answer.

Explanation:

An element is defined as a substance which cannot be broken down into simpler substances.

For example, potassium is a metal and it contains only atoms of potassium.

A compound is defined as a substance that contains two different elements which are chemically combined together in a fixed ratio by mass.

For example, $MgCl_{2}$ is a compound in which atoms are present in 1:2 ratio.

A mixture in which particles of one or more number of solutes are evenly distributed into the solvent is known as a homogeneous mixture.

For example, a mouthwash is a homogeneous mixture because it is a clear solution as all the components are evenly distributed.

On the other hand, a heterogeneous mixture is defined as the mixture in which solvent particles are unevenly distributed into the solvent.

For example, mud particles present in water is a heterogeneous mixture.

Thus, we can conclude that mouthwash is a homogeneous mixture.
