Cecilia,
Please check with your college legal department as to whether or not you may donate any chemicals. They may tell you that for liability reasons you may just have to dispose of them according to all local, state and federal regulations per EPA, HAZWOPER,, etc. If they say it is OK, please make sure that you donate only chemicals in their original, unopened packaging along with a copies of the most current SDS's from the various manufacturers. I would exclude from the list any chemicals which tend to be unstable due to heat, light, moisture, motion, oxygen, etc. sensitivity or were synthesized at the college and not purchased.
Good Luck!
All My Best,
