Usually, this means evaporating and concentrating the solution once all the solid has dissolved. The sequence involves first solubilizing the water insoluble amine by converting it into a water soluble amine hydrochloride, then decolorizing. If not, decant the hot solution or try to remove the particles with a spatula or Pasteur pipette while keeping the solution warm. Extraction: Suppose you allowed two immiscible liquids to come in contact with each other and and one of the liquids had a solute dissolved in it.
