In the shortened period today we did the Solution Formation Lab. The goal of the lab was to determine the effect of three variables on the solubility of copper sulfate in water. These variables were: crystal size, temperature, and degree of mixing. Based on my group's (Trevor B, Artie B, and myself...decide if you trust us or not) data, we came to the conclusion copper sulfate was most soluble under the following conditions:
- higher temperature
- smaller crystals
- and vigorous stirring
Conversely, the least soluble conditions are:
- lower temperature
- larger crystals
- and little to no stirring
And that's about it for today. Work on your Webassigns and the lab writeup is due Thursday. Until we meet again,

Joining you tomorrow will be the notorious Arthur B
