Please don't try to justify, in open forum discussion, your need for the 'bestest' grade or your personal problems, as the reason why we must do it all for you. Such behavior is offputting, when it happens between adults, and may cause you to suffer an unpleasant response, either here on the Chemical forums, or even in real life.
I thought salt might be alkaline because you can bathe wounds in it and I thought acid would burn on open skin.
Briefly, your statement is wrong. This is basic, high school level or even junior high school level, chemistry. I'm sorry you've missed out on such instruction, but your status now is what you (and all of us) have to work with. You could write an essay trying to justify your conclusion, but I also think its too lacking, and will likewise cost you points.
Try to think about in in some other way, since you're lacking chemistry to work with. And clearly, the class instructor doesn't mind that you lack basic chemistry, if this is how the class is taught. Are all acids dangerous to skin and wounds? Is your vinegar that dangerous? Since baking soda is alkaline, is tables salt the same sort of compound? Try to guess the project logically: they've given you an acid, a base and ...another base? Maybe they wouldn't do that?
