Is bicarbonate acid or alkali?

Explanation:
Bicarbonate acts as a base in acid–base chemistry. It is the conjugate base of carbonic acid, and in solution it accepts a proton to help neutralize acids, which raises pH. In physiological and clinical contexts, bicarbonate is associated with alkali behavior because it buffers and increases alkalinity rather than acting as an acid. While it can play different roles in special situations (amphiprotic), its common classification is as an alkali.
