In distillation separation, breaking of azeotropes can be achieved
a. by changing system pressure
b. by adding an entrainer
c. by adding a solvent and using liquid-liquid extraction
d. by all of the above methods

c) by adding a solvent and using liq-liq extraction

Explanation:

azeotrope is a liquid mixture of defined composition that boil a constant temperature and behaves as if it were formed by a single component.

when adding anhother compondent (solvent) , changes the molecular interaction and eliminates the azeotropes.

then in the liquid-liquid extraction, the component of  the solution distributed in inmiscibles phases are separated.

can you list the answers so i can answer
