The term 'suspension' in chemical mixtures refers to what?

The term 'suspension' in chemical mixtures specifically refers to solid particles that are dispersed throughout a liquid but are not dissolved in it. In this context, the solid particles maintain their individual properties and can often be seen within the liquid. This mixture requires agitation to stay in suspension, as over time, the solid particles may settle to the bottom due to gravity.

In contrast, a uniform mixture of substances would be referred to as a solution, where the solute is completely dissolved in the solvent. A volatile serum typically indicates a product with volatile components, often used for hair but does not define a suspension. Lastly, a treatment for scalp issues may incorporate suspensions, but defining the term itself does not specifically pertain to scalp treatments. Thus, recognizing that 'suspension' denotes the arrangement of solid particles in a liquid is crucial for understanding its application in various contexts, including hairstyling products.
