Lab 10.2

The graph that I had and Table G had many similatiries; ours was not very accurate due to the lack of plots on the graph. Since there was only 10g of water, the KClO3 may have dissolved much quicker than it should have.
To make the KClO3 dissolve quicker, we increased the temperature of the solution by putting it on a hot plate. When surface area is increased, meaning we have to crush up the KCLO3 there is more room for collisions resulting in more effective ones.The solution was unsaturated when the KClO3 was undissolved at the bottom of the test tube and it was saturated when the KClO3 was dissolved.




Enrichment:A saturated solution is created when making rock candy. With water you add as much sugar as will dissolve, and then heat the water to dissolve more creating a solution that is supersaturated. After, you add the string into the water on where the candy will form. As the water cools the super saturated solution has more sugar in it than it can possibly hold. This causes the sugar to come out of the solution forming a precipitate which is the crystals of the rock candy.
