Acid: Definition and Examples in Chemistry - …

13/1/2020· An acid is a chemical species that donates protons or hydrogen ions and/or accepts electrons.Most acids contain a hydrogen atom bonded that can release (dissociate) to yield a ion and an anion in water. The word acid comes from the Latin words acidus or acere, which mean "sour," since one of the characteristics of acids in water is a sour taste (e.g., vinegar or lemon juice).
