Chapter 16, Problem 16.3QP
Interpretation Introduction

Interpretation: Given set of species has to be classified as Bronsted acid or base, or both.

Concept Introduction: Bronsted's definition is based on the chemical reaction that occurs when both acids and bases are added with each other.  In Bronsted's theory acid donates proton, while base accepts proton from acid resulting in the formation of water.

Example: Consider the following reaction.

HCl+NH3NH4++Cl-

Hydrogen chloride donates a proton, and hence it is a Bronsted acid.  Ammonia accepts a proton, and hence it is a Bronsted base.

Bronsted base accepts a proton to give a protonated species known as conjugate acid and Bronsted acid loses a proton deprotonated species is known as conjugate base.  When a proton is removed the resulting species will have a negative charge and when a proton is added the resulting species will have a positive charge.

Answer to Problem 16.3QP

Answer

The species (a) is both Bronsted acid and Bronsted base.

The species (b) is Bronsted base.

The species (c) is Bronsted acid.

The species (d) is Bronsted base.

The species (e) is Bronsted acid.

The species (f) is Bronsted base.

The species (g) is Bronsted base.

The species (h) is Bronsted base.

The species (i) is Bronsted acid.

The species (j) is Bronsted acid.

Explanation of Solution

(a)

To classify: H2O as Bronsted acid or base, or both.

To identify the species as Bronsted acid.

H2OH++OH-

Water molecule loses a proton to form a conjugate base as shown above.  Therefore, water can act as Bronsted acid.

To identify the species as Bronsted base.

H2O+H+H3O+

  Water molecule accepts a proton to form hydronium ion.  Therefore, water can act as Bronsted base.

From this we can conclude that water can act as both Bronsted acid and Bronsted base.

(b)

To classify: OH- as Bronsted acid or base, or both.

To identify the species as Bronsted acid.

Hydroxide ion cannot lose a proton to form a conjugate base.  Therefore, hydroxide ion cannot act as Bronsted acid.

To identify the species as Bronsted base.

OH-+H+H2O

Hydroxide ion accepts a proton to form water molecule.  Therefore, hydroxide ion can act as Bronsted base.

From this we can conclude that hydroxide ion can only act as Bronsted base.

(c)

To classify: H3O+ as Bronsted acid or base, or both.

To identify the species as Bronsted acid.

H3O+H2O+H+

The hydronium ion can lose a proton to form a conjugate base as shown above.  Therefore, hydronium ion can act as Bronsted acid.

To identify the species as Bronsted base.

Hydronium ion cannot accept proton to form a conjugate acid.

From this we can conclude that hydronium ion can act only as Bronsted acid.

(d)

To classify: NH3 as Bronsted acid or base, or both.

To identify the species as Bronsted acid.

Ammonia cannot lose a proton to form a conjugate base.  Therefore, ammonia cannot act as Bronsted acid.

To identify the species as Bronsted base.

NH3+H+NH4+

Ammonia accepts a proton to form ammonium ion.  Therefore, ammonia ion can act as Bronsted base.

From this we can conclude that ammonia can act only as Bronsted base.

(e)

To classify: NH4+ as Bronsted acid or base, or both.

To identify the species as Bronsted acid.

NH4+NH3+H+

The ammonium ion can lose a proton to form a conjugate base as shown above.  Therefore ammonium ion can act as Bronsted acid.

To identify the species as Bronsted base.

Ammonium ion cannot accept proton to form a conjugate acid.

From this we can conclude that ammonium ion can act only as Bronsted acid.

(f)

To classify: NH2 as Bronsted acid or base, or both.

To identify the species as Bronsted acid.

NH2 cannot lose a proton to form a conjugate base.  Therefore, NH2 cannot act as Bronsted acid.

To identify the species as Bronsted base.

NH2+H+NH3

NH2 accepts a proton to form ammonia.  Therefore, NH2 ion can act as Bronsted base.

From this we can conclude that NH2 can act only as Bronsted base.

(g)

To classify: NO3 as Bronsted acid or base, or both.

To identify the species as Bronsted acid.

NO3 does not have a proton at all.  Therefore, this cannot lose a proton to form a conjugate base.  Hence, NO3 cannot act as Bronsted acid.

To identify the species as Bronsted base.

NO3+H+HNO3

NO3 accepts a proton to form nitric acid.  Therefore, NO3 ion can act as Bronsted base.

From this we can conclude that NO3 can act only as Bronsted base.

(h)

To classify: CO32 as Bronsted acid or base, or both.

To identify the species as Bronsted acid.

Explanation:  CO32 does not have a proton at all.  Therefore, this cannot lose a proton to form a conjugate base.  Hence, CO32 cannot act as Bronsted acid.

To identify the species as Bronsted base.

CO32+H+HCO3

CO32 accepts a proton to form HCO3 ion.  Therefore, CO32 ion can act as Bronsted base.

From this we can conclude that CO32 can act only as Bronsted base.

(i)

To classify: HBr as Bronsted acid or base, or both.

To identify the species as Bronsted acid.

HBrBr-+H+

The HBr can lose a proton to form a conjugate base as shown above.  Therefore, HBr can act as Bronsted acid.

To identify the species as Bronsted base.

HBr cannot accept proton to form a conjugate acid.

From this we can conclude that HBr can act only as Bronsted acid.

(j)

To classify: HCN as Bronsted acid or base, or both.

To identify the species as Bronsted acid.

HCNCN-+H+

The HCN can lose a proton to form a conjugate base as shown above.  Therefore, HCN can act as Bronsted acid.

To identify the species as Bronsted base.

HCN cannot accept proton to form a conjugate acid.

From this we can conclude that HCN can act only as Bronsted acid.

Conclusion

The given set of species are classified as Bronsted acid or base, or both.
