    The definition of basicity is the condition of being a base, or the difficulty for an acid to react with a base determined by the number of hydrogen atoms that can be replaced in the acid. An example of something that has basicity is water.

    It means the tendency of a compound to act as hydron (proton) acceptor. The basicity of a chemical species is normally expressed by the acidity of the conjugate acid.
