Distillation and Fractional Distillation
Distillation and Fraction Distillations
The purpose of distillation is to purify a liquid. Distillations are use to purify contaminates out of water to obtain clean pure water, as well as, to separate mixtures of liquids into their individual components; e.g. methanol and water.
Distill methanol from water using a simple distillation apparatus and fractional distillation apparatus to determine which is a more accurate form of distillation.
Chemical reaction and mechanism:
This experiment is conducted in three phases: 1) Phase I: Simple …show more content…
A 25 mL graduated cylinder was used to collect the 1 mL sample of the distilled solution as it dropped from the distillation apparatus. Due to lack of 10 mL graduated cylinders, a potential error could be that too much or too little solution was gathered; not an exact 1 mL sample was collected due to size of cylinder. This solution was then weighed and ran through the refractive index machine. An additional graduated cylinder was used to collect the next 1 mL sample while the 1st sample was being weighed and refractive index collected. To weigh the 1 mL sample, a small beaker was set in a zero gravity scale to be calibrated to zero, once calibrated, the 1 mL sample was transferred from the graduated cylinder to the beaker and
