Solution, Types of Solution, Properties of Solution, What is a Mixture, Characteristic of Solution.
The solution is a homogeneous mixture composed of a solute dissolved in a solvent and forming a single phase liquid. They can be categorized into several types based on the state of the solute and solvent, such as solid-solid, solid-liquid, liquid-liquid, and gas-liquid solutions. The properties of the solution include uniform composition, transparency, and the ability to pass through membranes via osmosis. Visit Nokryan.com in general.
