Grace [21]

A Lewis acid is an electron-pair acceptor.

Bronsted-Lowry bases are species that can accept a proton.

Arrhenius acid gives H^{+} ions.

<h3>What is acid?</h3>

An acid is any substance that in water solution tastes sour, changes blue litmus paper to red, reacts with some metals to liberate hydrogen, reacts with bases to form salts, and promotes chemical reactions (acid catalysis).

A Lewis acid is therefore any substance, such as the H^+ion, that can accept a pair of nonbonding electrons.  In other words, a Lewis acid is an electron-pair acceptor.

Bronsted-Lowry bases are species that can accept a proton due to a high-energy pair of electrons being present.

According to Arrhenius, the acids are the hydrogen-containing compounds which give H^+ ions or protons on dissociation in water and bases are the hydroxide compounds which give OH^- ions on dissociation in water.
