11. Here, the immiscible liquids separate into layers ( water below and solvent above it ). 12. immiscible liquids rotating around a vertical axis is an upward-opening circular paraboloid . ]]13. Two substances that can never mix to form a solution are called " immiscible ". 14. In this environment chalcopyrite is formed by a sulfide liquid stripping copper from an immiscible silicate liquid. 15. Because the zinc is immiscible in the lead it remains in a separate layer and is easily removed. 16. By contrast, substances are said to be immiscible if a significant proportion does not form a solution. 17. In liquid-liquid separation, a compound is distributed between two immiscible liquid phases under equilibrium conditions. 18. A compound that has two immiscible hydrophilic and hydrophobic parts within the same molecule is called an amphiphilic molecule. 19. Suppose you have two immiscible liquids in a beaker, with boiling points separated by 20 degrees or so. 20. Immiscible blends will phase separate and form a dispersed phase, which may improve physical properties ( figure 1 ).
