I can't find the answers to these two questions...could someone help me? Describe the process when a polar solvent dissolves an ionic substance. Why would SO2 go down in solubility when temperature increases? And while I'm thinking of it...my brother brought home his science book and, upon reading over it to help him with his work, I was reminded of just how much better having a textbook is. My Dad is looking into getting one from my public school for me to borrow but I don't think he's going to get one. If he can't, I was going to look into buying one. Does anyone have any suggestions? The only site I've found thus far (I haven't gotten to look around much...I've got homework out the butt to do.) is this one here.
