Acidity of a Compound
For Brønsted acids, acidity is the tendency of a compound to act as an H+ donor.
The acidity of a Brønsted acid can be quantitatively expressed by the acid dissociation constant of the compound in water or some other specified medium. The most familiar quantitative measure of acidity is the pH scale.
Typical examples of Brønsted acids are acetic acid and sulfuric acid.
For Lewis acids, acidity relates to the compound's ability to accept an electron pair. When a Lewis acid accepts an electron pair, it forms a covalent bond with the donor of the electron pair. The electron pair donor is a Lewis base. Lewis acidity can be quantitatively expressed by the association constants of the resulting Lewis adducts and π-adducts.
Typical examples of Lewis acids are CO2 and K+
Answer: Hello dear
Explanation: An acid is a chemical species that donates protons or hydrogen ions and/or accepts electrons. ... 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).
