Today in class we learned about the polar and non polar solvents

Polar and non-polar solvents

• Polar substances have an unequal distribution of changes.

and we did a lab - the objective was to determine if Glycerin is Polar or non-polar.
after mixing the test tubes, we noticed that the solvents water sugar- after mixing hte two dissolved. also the salt. some of the test tubes changed colors, for ex. iodine and the paint thinner. also after mixing iodine and water: it just changed colors from clear to brown, and it did not dissolve.

in the end we have conconluded that glycerin is polar because it mixed with water which is also a polar substance.
non polar can only react with non polar.
