Which type of mixture requires initial agitation?

A solution is a type of mixture that typically requires initial agitation to ensure that the solute is fully dissolved in the solvent. In a solution, components are uniformly distributed at the molecular level, which means the solute (the substance being dissolved) needs to be mixed thoroughly with the solvent (the substance in which the solute is dissolved) to achieve a homogeneous mixture.

When creating a solution, especially if the solute is in solid form and is being added to a liquid, stirring or shaking helps to break up the solute particles and allows them to interact with the solvent. This interaction leads to the solute entering the solution phase, resulting in an even distribution of the solute throughout the solvent.

In contrast, while emulsions, suspensions, and spray mixtures involve components mixed together, they may not always require the same degree of initial agitation, or their mixing processes can differ in nature. For example, emulsions may require an emulsifying agent to maintain stability but may not need continuous agitation once formed. Suspensions, while they may necessitate some stirring, are generally a heterogeneous mixture where particles can settle over time. Spray mixtures, often found in applications like aerosol products, tend to depend more on the method of application rather than initial mixing
