Chapter 15, Problem 15.29QE

(a)

Interpretation Introduction

Interpretation:

The product of reaction between NH3 and CH3COOH has to be identified. Also, the proton transfer in this acid-base reaction of NH3 and CH3COOH has to be shown.

Concept Introduction:

In Bronsted–Lowry theory, acid is defined as a substance that donates a proton. In a solution, it dissociates to give H+ ions. A solution can be water or made of any other substances. For example, HCl. All Bronsted–Lowry acids cannot be Arrhenius acids.

Base is defined as a substance that accepts a proton. In a solution, it dissociates to give OH ions. A solution can be water or made of any other substances.

Brønsted–Lowry acid transfer a proton and form base as the other compound can accept a proton. This is called conjugate acid-base pair. In pair of conjugate acid and base, the acid form is protonated and the base form lost the proton.

Every base has a conjugate acid. They are related by loss or gain of proton. The expression for base and conjugate acid is as follows:

  Base+ProtonConjugate acid

Every acid has a conjugate base. They are related by loss or gain of proton. The expression for conjugate base and acid is as follows:

  AcidProton+Conjugate base

The reaction mechanism in which proton is donated by a compound and accepted by the other compound is called a proton transfer reaction. It involves transfer of protons between two species in chemical reaction.

(b)

Interpretation Introduction

Interpretation:

The product of reaction between has CO32 and N2H5+ to be identified. Also, the proton transfer in this acid-base reaction of CO32 and N2H5+ has to be shown.

Concept Introduction:

Refer to part (a)

(c)

Interpretation Introduction

Interpretation:

The product of reaction between OH and H3O+ has to be identified. Also, the proton transfer in this acid-base of OH and H3O+ reaction has to be shown.

Concept Introduction:

Refer to part (a)

(d)

Interpretation Introduction

Interpretation:

The product of reaction between HCOO and HSO4 has to be identified. Also, the proton transfer in this acid-base reaction of HCOO and HSO4 has to be shown.

Concept Introduction:

Refer to part (a).
