Which of the given statements is true concerning azeotropes?
Understanding Azeotropes
An azeotrope is a mixture of two or more liquids that boils at a constant temperature, without undergoing any change in composition. The vapor produced from an azeotropic mixture has the same composition as the liquid mixture itself.
The vapor of an azeotrope has the composition of one of the pure components of the mixture. The correct statement concerning azeotropes is option b. The vapor of an azeotrope has the composition of one of the pure components of the mixture.
An azeotrope is a mixture of two or more liquids that boils at a constant temperature, without undergoing any change in composition. The vapor produced from an azeotropic mixture has the same composition as the liquid mixture itself.
For example, a mixture of ethanol and water forms an azeotrope with a composition of 95.6% ethanol and 4.4% water. When this mixture is boiled, the vapor produced will also have the same composition.
An azeotrope represents a blend of two or more liquids that sustains an unchanging composition throughout distillation or similar separation procedures, implying it possesses a consistent boiling point. Within an azeotropic mixture, the vapor formed retains an identical composition as the liquid mixture. This behavior arises from distinct interactions occurring among the components within the mixture.
Which statement is true concerning azeotropes? a. Only a mixture of two compounds is considered to form an azeotrope. b. The vapor of an azeotrope has the composition of one of the pure components of the mixture. c. Liquids that have completely different properties do not form azeotropes. d. Only a mixture of three compounds is considered to form an azeotrope. e. An unknown liquid that boils at a constant temperature is always classified as pure. f. The vapor of an azeotrope has the same composition as the unboiled mixture. The correct statement concerning azeotropes is option b. The vapor of an azeotrope has the composition of one of the pure components of the mixture.
