Vinegar or acetic acid is rather weak and is just about only good for making pickles and model volcanoes while HCl or hydrochloric acid is very strong and is what digests and beaks down food in your stomach and is the reason your throat burn when you vomit.
At the beginning of this lesson, there was a question about two acids. Vinegar, which contains acetic acid, is used in foods and has few safety concerns. Hydrochloric acid is used in chemistry labs and requires the use of safety goggles and gloves. Why do the safety concerns for these two acids differ?
