WebSolubility is the ability of a substance (the solute), to mix into a liquid (the solvent).. It measures the highest amount of substance mixed into a liquid solvent while they are both at equal amounts. When the two mix together it is called a saturated solution.Certain substances can mix into any amount of a liquid solvent. WebA solvent is a substance that dissolves a solute resulting in a solution. Solvents can be classified into two categories: polar and non-polar. Polar solvents contain bonds …
