Distillation Lab
Reference pg. 78 to determine equipment and set up required to purify foul water.
Make sure your equipment is clean. The boiling flask will not come completely clean
and that is not essential. But it is essential that your condensing tube, and collecting
beaker are scrupulously clean.
Purpose: To purify a sample of foul water.
Measure the volume before and after purification. The amount of foul water you
purify should be based on the size of your boiling flask, only fill your boiling flask
about half full. If your boiling flask is 125mL then use approximately 63mL of foul
water.
Test electrical conductivity before and after purification (clean the conductivity
apparatus before testing purified water)
Collect qualitative data before and after purification, (brainstorm with your lab
partners and determine what qualitative data should be collected)
Classify the matter(foul water) before and after purification (reference your
classification of matter notes)
Do not distill to dryness leave some of the foul water in the boiling flask
