Solubility and functional groups _____ you will recall from general chemistry that a solution has two components: the solvent, which is the substance present in greater amount, and the solute, which is dissolved in the solventsolubility is defined as the mass (in grams) of solute dissolved in 100 g of solute at saturation.
