How does a true solution behave after mixing?

A true solution behaves in a way that is characterized by uniformity and stability after mixing. When a solute is completely dissolved in a solvent, it forms a homogenous mixture where the individual components cannot be easily distinguished. This means that the particles of the solute are dispersed at the molecular level throughout the solvent, resulting in a stable solution that does not separate or settle out over time.

This property of true solutions is crucial in many applications, including those in agricultural practices and pesticides, where consistency in the formula is essential for effectiveness. The uniformity ensures that every part of the solution has the same concentration of active ingredients, which is vital for efficacy and safety.

In contrast, other behaviors described in the options would indicate that the mixture is not a true solution, such as forming layers, needing stirring to stay mixed, or requiring additional components to maintain stability. These phenomena typically pertain to suspensions or emulsions, which can separate or necessitate mechanical agitation to remain homogenized.
