Soluble

adj. capable of being melted or dissolved in a solvent; able to be solved, explainable

n. soluble element, element which is capable of being dissolved in a solvent

Solubility is a physical property referring to the ability for a given substance, the solute, to dissolve in a solvent. It is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium. The resulting solution is called a saturated solution. Certain substances are soluble in all proportions with a given solvent, such as ethanol in water. This property is known as miscibility.
