VDistinction Level BTEC Applied Science Assignment C, Chromatography. Soluble :solubility is the degree to which a substance dissolves in a solvent to make a solution Solvent : the substance in which a solute dissolved to produce a homogeneous mixture Mobile phase : the liquid that transports the substance mixture through the absorbing material which travels along the stationary phase and carries the substance components with it Stationary phase : the solid material that absorbs the mixture ...
