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.
Why is it difficult to obtain 100 percent oxygen from fractional distilation?
It forms an azeotrope.
Where would the boat produce the highest concentration of carbon monoxide?
A boat produces the highest concentration of carbon monoxide in the exhaust system.
What is the system devised to measure the hydrogen ion concentration in a solution?
pH

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.
Difference between azeotrope solution and normal solution?
azeotrope can't be distillation and normal solution can distill by simple heatup the solution

When the concentration of a solute is the same throughout a system system has reached?
The System will reach EQUILIBRUIM.
Is R-134A an azeotrope or zeotrope?
Refrigerant R-134a is zeotrope is a single compound.
What three types of testers can be used to determine the concentration of antifreeze in a cooling system?
what three types of testers can be used to determine the concentration of antifreeze in a cooling system?
How to write the N concentration in SI system?
n
The pH scale is a measurement system that indicates the concentration of these in a solution?
The pH scale is a measurement system that indicates the concentration of Hydrogen ions also called Protons.
What is the measurement system called that indicate the concentration of H ions in solution?
The pH system is used to indicate the concentration of hydronium ('H+') ions in solution. It is governed by the equation pH = -log[H+]
