Acid

Acid is a very dangerous substance, that needs to be handled with care. If the acid has a higher concentration, it can do more damage to the human body. If it is diluted, it may just make the area of contact red. Acid burns look like a regular first, second, or third degree burn. If highly burned, corrective surgery is required. Hydrofluoric acid is the most dangerous acid, and can do a lot of damage. When inside the body, it burns you from the inside out. The fluoride ions bond to the calcium in the bones, which can lead to heart failure, which is more dangerous than burns. The fluoride also clogs blood vessels and tears up tissues. Not only is the acid itself dangerous, but the fumes are as well. Always wear proper protective gear when handling any acid.
