My chem ISU involves taking a product in existance already and redesigning it (chemically) to become more environmentally friendly. These terms are very loose, and so, in my brainstorming, I've been thinking of using lemon juice or lemon OIL even (not sure how to extract the oil though) and creating a vinegar-lemon cleaner mix. Now, done in-depth, I'm sure I could get full marks like this, but I think I'm interested in gearing this project towards something more specific, and pulling up ship at some sort of hot tub chemical. I work at a pool store, and know that there are several hot tub cleaners such as polishes for the fiberglass, and whirlpool rinse which degreases the pipes. On the downside to the vinegar nad acid mix, using it in a full hot tub (as a chemical to treat the tub water while full) means significantly lowering pH. Perhaps this could be a feature to the chemical? PErhaps not. Anyways, I guess what I want to get at here is: USing a vinegar-lemon mix, is there any way that myself and my partners could make this chemical more specialized? Perhaps a lemon scented polish that cleans the scale off of floor model hot tubs for pool companys ;) ? Either way, I dont want to make a simple watery mixture of vinegar and lemon that we can slap a label on and say it "cleans a huge load of things"... I would prefer to make something with a little more meaning. Even if that means somehow making a slightly more "goey" consistency in order to create a polish. Throw out ideas, even if there are missing gaps in it and myself and others here I'm sure may be able to fill those in from brainstorming! All ideas (within capable doing) will be seriously considered. We're grade 11 high school students so we dont exactly have our hands on any $500 million chem labs, but we'll see what we can do for some of this stuff, if you can think of anything.. Thanks in advance!
