Chapter 13, Problem 140QP

Interpretation Introduction

Interpretation:

From all the given chemical species, the conjugate base of ${\text{H}}_{\text{3}}{\text{PO}}_4^{-}$ is to be identified.

Concept Introduction:

An acid and its conjugate base are different with respect to the hydrogen. An acid always tends to donate its proton and produces its conjugate base. In an acid-base reaction, an acid always donates its proton and a base always accepts proton in accordance with the “Brønsted–Lowryâ€� acid-base concept.
