Chapter 9, Problem 23P

Interpretation Introduction

Interpretation:

The species that can form Bronsted-Lowry bases should be selected from the following:

  ${\text{OH}}^{\text{-}}{\text{; Ca}}^{2+}{\text{; C}}_{\text{2}}{\text{H}}_{\text{6 }}{\text{; PO}}_4{}^{\text{3-}}{\text{; OCl}}^{\text{- }}{\text{; MgCO}}_3$

Concept Introduction:

A substance is said to be acidic if it can give hydrogen ions ( ${\text{H}}^{\text{+}}$ ) whereas a base is said to be a substance that can give ${\text{OH}}^{\text{-}}$ ion. This theory of acid and base is called the Arrhenius theory of acid and base.

Another theory that is purposed by Bronsted and Lowery is said to be Bronsted-Lowry acid-base theory. It states that acid can give ${\text{H}}^{\text{+}}$ ions whereas a base can accept the ${\text{H}}^{\text{+}}$ ion in its solution. Hence, this theory is entirely based on the presence of ${\text{H}}^{\text{+}}$ ion in the given substance. A Bronsted base form conjugated acid of it after accepting ${\text{H}}^{\text{+}}$ ion.
