Acid | Definition, Examples, Types, Uses, Facts | Britannica Acid, any substance that in water solution tastes sour, changes the color of certain indicators (e g , reddens blue litmus paper), reacts with some metals (e g , iron) to liberate hydrogen, reacts with bases to form salts, and promotes certain chemical reactions (acid catalysis)
ACID Definition Meaning - Merriam-Webster The meaning of ACID is a sour substance; specifically : any of various typically water-soluble and sour compounds that in solution are capable of reacting with a base to form a salt, redden litmus, and have a pH less than 7, that are hydrogen-containing molecules or ions able to give up a proton to a base, or that are substances able to accept
