A mixture of water and non-dissolved material is known as what?

Solution
Emulsion
Suspension
Blend

The correct answer is: Suspension

A mixture of water and non-dissolved material is classified as a suspension. In a suspension, the solid particles are dispersed throughout the liquid but do not dissolve in it. This means the particles remain visible and may settle at the bottom of the container if left undisturbed. This characteristic distinguishes suspensions from solutions, where the solute is completely dissolved in the solvent and cannot be seen. Emulsions refer to mixtures of two immiscible liquids where one is dispersed in the other, such as oil and water, and typically require emulsifying agents to stabilize them. A blend, while it can refer to a simple mixture, does not specifically imply the presence of non-dissolved particles in water. Understanding these definitions helps in various aspects of hairstyling, especially when mixing products or treatments that may involve water and other ingredients.
