Find the solubility of aspirin in water at a range of temperatures between 0 degrees C and 100 degrees C?

Answer 1

This sounds like an experiment. You should heat and chill a known volume of water (but new water each time) to various temperatures between 0 and 100 degrees C, and dissolve aspirin in it until no more can be dissolved. If you discretize the aspirin so that you are adding, say, 1 g at a time, you'll know the added mass of aspirin to within 1 g when you note that no more is dissolving. Divide the mass of aspirin that was added by the known volume of the water to get the solubility at that temperature. Once you have found the solubility at a range of temperatures, see what conclusions you can draw from the data. I suspect you'll find that the solubility of aspirin in water increases linearally with temperature.
