Answer:
none
Explanation:
a - zeo - tropic = ‘not’ - ‘boil’ - ‘change’ (can’t be changed by boiling / distillating)
From Greek:
a- is a negating prefix (E.g. morphe = form, amorphous = without form).
zeo is the verb ‘to boil’.
trepo is the verb ‘to change’, from which the adjective tropikos (tropic in English) is formed as something which changes or can be changed.
- In case of Azeotropic mixture, both components boil at nearly equal temperature so liquid phase and vapor phase have same composition. Therefore, these methods are not effective.
- Generally to further distill azeotropes you need The addition of a material separation agent. Such as benzene to water/ethanol mixture. Different agents for different azeotropes.
