Answers
Explanation:
An acid is a molecule or ion capable of donating a proton, or, alternatively, capable of forming a covalent bond with an electron pair
Explanation:
Definition of Acid
The term acid and base have been defined in different ways depending on the particular way of looking at the properties of acidity and basicity. Arrhenius first defined acids as compounds which ionize to produce hydrogen ions, and bases as compounds which ionize to produce hydroxide ions. According to the Lowry-Bronsted definition, an acid is a proton donor and a base is a proton acceptor.
According to the Lewis definition, acids are molecules or ions capable of coordinating with unshared electron pairs, and bases are molecules or ions having unshared electron pairs available for sharing with acids. To be acidic in the Lewis sense, a molecule must be electron deficient. This is the most general acid base concept. All Lowery Bronstead acids are Lewis acids but, in addition, the Lewis definition includes many other reagents such as boron trifluoride, aluminium chloride etc.
