What Does “soluble” Mean in Science?

When something can be dissolved or liquefied in the presence of another substance, it is considered soluble by scientific standards. The degree of solubility can vary. Substances can be completely insoluble, soluble only under certain conditions or extremely soluble under most conditions.

The solubility of a substance is highly dependent on the relationship between the solute and the solvent. The solute is the substance that dissolves, while the solvent is the substance into which the solute dissolves. The stronger the attraction between the solute and the solvent, the greater the solubility of the substance. When the attraction is weak, there is less solubility. When a solute dissolves into a solvent, the resulting substance is called a solution.
