Azeotropes are binary mixtures having same composition in liquid state as well as vapor state and boil at constant temperatures.
Liquids forming azeotropes cannot be separated using common techniques like Fraction Distillations.
There are two types of Azeotropes.

Which is the azeotrope concentration of water-xylene system?
water and m-xylene azeotrope at 94.5C, 40% h2o, 60%xylene
Why is it difficult to obtain 100 percent oxygen from fractional distilation?
It forms an azeotrope.
Why theoretical value of ethanol in distillation process is differ with experimental value?
While the distillation is going on ,at 94.6% ethanol-water mixture forms an azeotrope which hampers further distillation.So ethanol cannot be made 100% pure.But concentration of ethanol can be increased by breaking the azeotrope by addition of benzene in large amount.
How do you separate benzene from dimethylformamide?
you can try distillation. benzene has a boiling point of 80 deg C and DMF is more like 150 deg C. i don't think it will form an azeotrope (may be wrong though). if it does form an azeotrope and the concentration of DMF is not too high, you can try washing the distillate in a sep funnel with water. DMF is freely miscible in water, whereas benzene is non-soluble in water.

Which is the azeotrope concentration of water-xylene system?
water and m-xylene azeotrope at 94.5C, 40% h2o, 60%xylene
Difference between azeotrope solution and normal solution?
azeotrope can't be distillation and normal solution can distill by simple heatup the solution
Ethyl acetate and water forms an azeotrope?
Yes, the boiling point of the azeotrope is 70.3 °C and contains 8.5 wt% water. see: http://www.solvent--recycling.com/azeotrope_1.html
Why is it difficult to obtain 100 percent oxygen from fractional distilation?
It forms an azeotrope.
Is R-134A an azeotrope or zeotrope?
Refrigerant R-134a is zeotrope is a single compound.
What is pressure swing adsorption?
Pressure Swing Adsorption refers to the process of purification of Hydrogen gas which is manufactured in a plant like rfinery. Hydrogen which is formed as a by-product in process like Reforming is also used as a raw material within the refinery process like Hydrotreating and Isomerization. So it has to be made impurities free for use. So Hydrogen is purified by the process known as pressure swing adsorption in which impurities are adsorbed on the surface and Hydrogen becomes clean.
What is the mathamatical term for mean?
The mathematical term for "mean" is "mean".The popular, or colloquial term for "mean" is "average".
