Result+of+Other+Group's+Procedure

We followed the procedure of the lab group consisting of Erik J., Greg G, Noelle K., and Sam K.

Procedure:

1) Pipette out all the oil at the top of the dirty water

//Seems like the group made it pretty difficult from step one to filter out the oil// //Our group used a simpler method// //We thought it would be easier to filter out the water first because it the majority of the mixture, but that is not what they called for.// //As we pipette out the oil at the top, we felt this step was not very productive and inaccurate.//

2) Use cone filter to remove dirt

//The dirt was successfully removed from the mixture using the filter paper and cone filter.//

3) Use cone filter once again to try to remove dirt

//Not very effective, this step is not very useful, kind of redundant, but color did change excessively so maybe not so useless after all//

4) Filter liquid again but add rocks to bottom of cone filter

//Rocks did nothing, useless, mixture looks the same// //NOTE: Never said how many rocks to put in//

5) Filtered the liquid in charcoal

//Charcoal was successful in filtering out yellow color/ substance in water mixture// //NOTE: Never specified an unit measurement of how much charcoal to put in//

//6)// Condenser

RESULT: How to know if water is distilled: -clear (yes) -colorless (yes) -odorless (smells kind of like oil)

Discussion: In comparison to our lap group's procedure and the other group's, they were done very differently. We felt our process was done much simpler whereas theirs was more complex. In the end, though, we both had the same result. Both groups came out with pure water.
