<P> In chemistry, a solution is a homogeneous mixture composed of two or more substances . In such a mixture, a solute is a substance dissolved in another substance, known as a solvent . The mixing process of a solution happens at a scale where the effects of chemical polarity are involved, resulting in interactions that are specific to solvation . The solution assumes the phase of the solvent when the solvent is the larger fraction of the mixture, as is commonly the case . The concentration of a solute in a solution is the mass of that solute expressed as a percentage of the mass of the whole solution . </P> <Ul> <Li> A solution is a homogeneous mixture of two or more substances . </Li> <Li> The particles of solute in a solution cannot be seen by the naked eye . </Li> <Li> A solution does not allow beams of light to scatter . </Li> <Li> A solution is stable . </Li> <Li> The solute from a solution cannot be separated by filtration (or mechanically). </Li> <Li> It is composed of only one phase . </Li> </Ul>

The relative amount of solute and solvent in a solution is defined as the
