Final answer:
A solution is a homogenous mixture consisting of a solute dissolved into a solvent. Solubility refers to the extent to which a substance can be dissolved in a solvent.
Step-by-step explanation:
A solution is a homogenous mixture consisting of a solute dissolved into a solvent. The solute is the substance being dissolved, while the solvent is the dissolving medium. The extent to which a substance can be dissolved in a solvent is its solubility, which is defined as the maximum concentration of the substance that can be achieved under specified conditions. Substances with relatively large solubilities are soluble, while those with relatively low solubilities are insoluble.
