POLAR/NONPOLAR LAB

Today's lab was on polar and non polar solutions/substances. We took paint thinner, water, glycerin, salt and sugar. We mixed them accordingly, and learned that paint thinner and water do not mix because water is nonpolar and paint thinner is polar. This then draws our conclusion that "likes" mix, and differences DON'T mix. Polar mixes with polar, and nonpolar mixes with nonpolar. Although the paint thinner and water were almost the same colour, you were able to see the layer where they met. Salt didn't dissolve in the paint thinner, also because they are not "alike."
