Okay, to start, I'm not a student, I don't know much about chemistry. I'm actually a waitress at a local bar. So chemistry really isn't my strong point. But I do know what sulfur smells like; rotten eggs. Let me pose my question like this: When I wipe out the ashtrays at work, I use a mixture of vinegar and water. When I do, and the water/vinegar mixes with the cigarette ashes, I always smell sulfur. Since I do this on the patio, I can't think of anything else it could be. So, am I accidentally making some kind of sulfur or something similar when I mix vinegar with cigarette ashes? (I honestly ask out of ignorance, please don't talk down to me and make me feel any more stupid. Thank you!)
