Explain the principle upon which separation is achieved in a distillation column.
aalyn [17]

Answer:

The fundamental principle involves the formation of equilibrium and separation into distillate and bottoms governed by the equilibrium composition curve , number of stages and the purity with which the distillate is required.

Explanation:

Distillation is a type of the separation process by physical means of a mixture on basis of its difference in boiling point or vapor pressure .  

Where we can just heat the mixture and separate out the components i.e the component with lower boiling point will form vapor easily and can be later condensed whereas the component with higher boiling point will remain as residue.

In case of a distillation column the same principle is applied at different stages to separate multiple components .The stages are known as trays or plates . In general , there is a certain liquid on each of the plate, and the arrangements are made for the ascending vapors to pass through the liquid and make contact with it . The fundamental principle involves the formation of equilibrium and separation into distillate and bottoms governed by the equilibrium composition curve , number of stages and the purity with which the distillate is required.

When we react a weak acid with a strong base of equal amounts and concentration, the component of the reaction that will have th
Svetllana [295]

Answer and explanation:

Initially, the pH of the solution will be determined by the dissociation of the weak acid.

Usually, this kind of solution consists of a mixture of weak acid that has not yet reacted and the salt that will be formed by the reaction of the weak acid with a strong base that has been added.

After the dissociation process, the pH will be more affected due to the excess of base in the solution.
