What are Azeotropes? Explain.
Answers
Azeotropes are a mixture of at least two different liquids. Their mixture can either have a higher boiling point than either of the components or they can have a lower boiling point. Azeotropes occur when fraction of the liquids cannot be altered by distillation. Typically when dealing with mixtures, components can be extracted out of solutions by means of Fractional Distillation, or essentially repeated distillation in stages (hence the idea of 'fractional'). The more volatile component tends to vaporize and is collected separately while the least volatile component remains in the distillation container and ultimately, the result is two pure, separate solutions.
An Azeotropic Mixture is a mixture of two real, miscible liquid which boil and distil at a constant temperature without undergoing any charges in composition.
minimum - boiling point azeotropic is formed while.
maximum boiling point azeotropic is formed. An Azeotropic Mixture cannot be separated into pure components by fraction distillation. A liquid mixture which distils with a changein composition is called a zeotropic mixture.
