Which will form maximum boiling azeotrope:a)C6H6 + C6H5CH3 solutionb)H...
Boiling Azeotrope:
A boiling azeotrope is a mixture of two or more liquids that have a constant boiling point and composition throughout the boiling process. This means that the vapor produced during boiling has the same composition as the liquid mixture.
Maximum Boiling Azeotrope:
The maximum boiling azeotrope is a type of boiling azeotrope in which the boiling point is the highest possible for that particular mixture. This means that the mixture cannot be separated by distillation because the vapor produced during boiling has the same composition as the liquid mixture.
Explanation:
Out of the options given, the maximum boiling azeotrope is formed by HNO3 and H2O solution. Here's why:
- C6H6 and C6H5CH3 solution: These are two different hydrocarbons with different boiling points. Therefore, they cannot form a boiling azeotrope.
- C2H5OH and H2O solution: This is a common example of a boiling azeotrope, but it is not a maximum boiling azeotrope. This is because the boiling point of the mixture is lower than the boiling point of pure ethanol. This means that the mixture can be separated by distillation.
- n-hexane and n-heptane: These are two different hydrocarbons with different boiling points. Therefore, they cannot form a boiling azeotrope.
- HNO3 and H2O solution: This is a maximum boiling azeotrope. The boiling point of the mixture is higher than the boiling point of pure HNO3 and pure H2O. This means that the vapor produced during boiling has the same composition as the liquid mixture, and the mixture cannot be separated by distillation.
Therefore, option B, HNO3 and H2O solution, forms the maximum boiling azeotrope.
