- The liquid-liquid extraction technique takes advantage of the solubility difference of a given compound in two immiscible solvents. Group of answer choices True FalseThis refers to a point wherein both liquid phases have the same composition. Hence, extraction is not possible. Liquidus Plait point Convergence point Tie linesTRUE or FALSE. Extraction is attained when the solute is completely dissolved and the concentration of the solution so formed is uniform. The concentration of the liquid retained by the solid leaving any stage is the same as that of the liquid overflow from the same stage.

Each colour of ink will get carried a different distance by the water, allowing you to see all of the different inks. Try this with different colours to see what actually goes into a colour. This technique is called chromatography and can be used in chemistry to find out what is in an unknown mixture. II. Materials .Felt tip pens (non-washable) . Kitchen roll .A bowl or cup .
