Answer:
Miscible solutions: The solutions which dissolve completely and form true solution are called miscible solutions.
Immiscible solutions: The solutions in which suspension is left is known as immiscible solutions.
Partially miscible solutions: The solutions which do not dissolve or do not suspend are called partially miscible solutions.
Explanation:
- Examples of miscible solutions are salt water, sugar water, dil. HCl etc..
- Examples of immiscible solutions are sand water, CaCO₃ in water as white precipitate etc...
- Examples of partially miscible solutions are synthetic gum in water etc...
Separating the solutions by chemical methods:
- We can separate gasoline and kerosene by fractional distillation.
- As gasoline is a petroleum product which is not soluble in water we can separate them by decantation. We can also separate them by setting the temperature at 100°C.
- Depending on the organic solvent's efficiency with dissolving ethanoic acid and it's melting point, you might be able to crystallize the ethanoic acid at very low temperatures.
- After settling of the mixtures, you can decant of the oil.
Hope this answer is helpful for you, if it is please rate it.
Thank you...
