Question

Do polar and non-polar substances mix? how to write a lab report on it.

Answer 1

Most polar substances will not mix with most non-polar substances.

Answer 2

how could i describe that in my lab report for the results and conclusion?

Answer 3

Did you do an experiment? Did you get results? Did you observe non-polar substances dissolving in polar solvents and vice versa? Results and conclusions come from your experimental observations. Hopefully they will agree with the general theme that "like dissolves like."

Answer 4

YES THAT NONE OF THEM COMBINES TOGETHER

Answer 5

If your experimental results don't disagree with the general statement, then why not write, "Polar solvents dissolved polar compounds and did not dissolve non-polar compounds while non-polar solvents dissolved non-polar compounds and did not dissolve polar compounds." That's a little wordy and a long sentence but you can edit it to make it sound better.

Answer 6

how could i list them in a chart?

Answer 7

I can't make spaces so I will use dashes to separate columns.
----polar solvent--- for example water
solute--p--n/p-- soluble(Y/N)
NaCl----x-- n/a-- Y
KCl ----x-- n/a-- Y
NaHCO3--x-- n/a -- Y
fat-----n/a--x---- N

The above is an example of a able that could be made for one of the polsr solvents. the x marks or a check mark to indicate it is polar or non-polar and a n/a (not applicable) or just leave it blank if you have marked it as polar. Then y or n for soluble or not soluble. A similar chart could be made for non-polar solvents. I don't know the extent of your experiment or what you used as solvents but you may be able to take this idea and distill it to something useful.
