acid...
An acid is a chemical substance, usually a liquid, which contains hydrogen and can react with other substances to form salts. Some acids burn or dissolve other substances that they come into contact with.

The pH scale measures how strong an acid or alkali is. If it is midpoint on the scale, it is considered neutral – the concentration of hydrogen ions is equal to the concentration of hydroxide ions.
