Today our class had to determine if glycerin is either polar or non-polar. In our first observations we mixed water with table salt and sugar and they both dissolved in the water. When we mixed water with iodine is it did not dissolved. When we mixed paint thinner with table salt and sugar it did not disslove but when we mixed paint thinner and Iodine it dissolved. In our second observations we mixed water and glycerin and it was soluble. When we mixed paint thinner adn water is was not soluble. we concluded that when we mix two of the same substances [polar-polar OR non polar- non polar] it is not soluble, but when we mix two different substances [polar - non polar] it is soluble
