Lab 10.2 - Solubility vs Temperature

In this experiment you used potassium chlorate to make a solubility curve that is similar to the ones that are found on Table G.

Look at the solubility curve on table G 

Compare your solubility curve to the actual solubility curve. Compare any parts that are similar or different. Obviously you used 10g of solvent instead of 100g, so explain how that affected your graph.

What things made a significant difference in how quickly the KClO3 dissolved. If you wanted to get something to dissolve quickly, what things can you do in order to make it happen. The more important question is: Why does this happen at the particle level, what does particle collisions and attractions have to do with this? Does surface area relate to this at all, and if it does what can you do to change that variable to make it happen quicker.

Describe how the terms unsaturated, saturated, and super saturated apply to the experiment. At what point was the solution saturated, and at what point was it unsaturated. I will tell you now that with potassium chlorate in this experiment, you never formed a supersaturated solution, it precipitated out before that happened.

ENRICHMENT: Find out how rock candy is made. I am sure you can find a recipe very easily, but I want you to apply this to chemistry using the vocabulary we have learned. This is a little more difficult task than just finding the recipe. If you want make it, try it, it is delicious.
