what is this stuff?
Yesterday I went to put gas in my car when I noticed my gas cap was gone. At first I thought I must have forgot to replace it after fueling up the previous time but then I noticed something else: a pale yellow powdery substance all around the opening to the gas tank. I realized then that someone must have removed my gas cap (and kept it) and then attempted to add the powdery substance to my gas tank. I assume this was the work of vandals and probably not too serious of a prank since my car seems to be running fine, but I am still very concerned about what this substance actually was. Mainly I am concerned that it was something potentially explosive. A friend of mine said it looked like residue from a fire extinguisher but my gut instincts tell me it’s something else. I do have a sample of the powder. Anybody know how I might go about indentifying this substance without having to pay a lab to do this?
Well, what I know is that when lead evaporates, it can leave a yellow stain. Sulfur can also. But I’m not a chemist, I don’t know exactly what you’re dealing with.
Insult anybody lately? LOL
Just joking around, but hey, I hope you get this problem sorted out. =)
