Vapor Pressure
« on: October 04, 2012, 09:46:43 PM »
I am stuck on a question regarding vapor pressure:

What effect might be introduced into the qualitative determination of vapor pressure by the saturation of the air in the burette with water vapor?

Prior to this, we did an experiment that had to do with an inverted burette filled with water, then air was let into it (about 6 inches) by opening the stopcock, then volatile liquids were put into the burette with a dropper (they were insoluble so they floated to the top of the burette) then from the change in water level, we could place the liquids in a decreasing order of vapor pressure.

To begin to figure this out, we'll have to understand what results your experimental procedure got.  Also, can you define for us -- "qualitative"?  Compare the technical definition to the results you got.
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.
