Chapter 14, Problem 14.41CP

(a)

Interpretation Introduction

Interpretation:

Among the given molecules and ions the one that can behave as Bronsted-Lowry acid and can behave as a Bronsted-Lowry base has to be identified.

Concept Introduction:

Bronsted-Lowry acid and bases:

The chemical species which is able to donate hydrogen ion to other substance known as B-L acid and the species which is able to accept hydrogen ion from another species known as B-L base.

Strong acid is $100\%$ ionized in an aqueous solution and strong base is $100\%$ protonated in an aqueous solution, so the concentration of ${\text{OH}}^{-}$ ion equals to the initial concentration.

(b)

Interpretation Introduction

Interpretation:

Among the given molecules and ions the one that can behave as Lewis acid and can behave as Lewis-base has to be identified.

Concept Introduction:

Lewis acid and base:

In Lewis acid-base reactions, the base donates pair of electron to an acid to forms covalent bond.  Other hand Lewis acids are electron pair acceptor and Lewis base are electron pair donor.
