Textbook Problem

In each of the following acid-base reactions, identify the Brønsted acid and base on the left and their conjugate partners on the right.

  1. (a) C2H5N(aq) + CH3CO2H(aq) ⇄ C5H5NH+(aq) + CH3CO2(aq)
  2. (b) N2H4(aq) + HSO4(aq) ⇄ N2H5+(aq) + SO42−(aq)
  3. (c) [Al(H2O)6]3+ (aq) + OH(aq) ⇄ [Al(H2O)5OH]2+ (aq) + H2O+()

(a)

Interpretation Introduction

Interpretation:

Bronsted acid and base on the left and their conjugate partners on the right has to be identified.

C5H5N (aq) + CH3CO2H (l) C5H5NH+(aq) + CH3CO2-(aq)

Concept Introduction:

Bronsted –Lowry definitions:

A Bronsted –Lowry acid is a proton donor, it donates a hydrogen ion, H+

A Bronsted-Lowry base is a proton acceptor, it accepts a hydrogen ion H+.

Bronsted –Lowry conjugate acid-Base pairs:

When an acid is dissolved in water, the acid (HA) donates a proton to water to form a new acid (conjugate acid) and a new base (conjugate base).

Explanation

C5H5N (aq) + CH3CO2H (l) C5H5NH+(aq) + CH3CO2-(aq)

In the above reaction,

CH3COOH is donated a proton to C5H5N. Therefore, CH3COOH is a Bronsted acid.

C5H5N is accepted a proton from CH3COOH. Therefore,C5H5NH is a Bronsted base.

The conjugate base of CH3COOH is CH3COO- because it has one proton less than CH3COOH

(b)

Interpretation Introduction

Interpretation:

Bronsted acid and base on the left and their conjugate partners on the right has to be identified.

 N2H4(aq) + HSO4- (aq) N2H5+ (aq) + SO42-(aq)

Concept Introduction:

Bronsted –Lowry definitions:

A Bronsted –Lowry acid is a proton donor, it donates a hydrogen ion, H+

A Bronsted-Lowry base is a proton acceptor, it accepts a hydrogen ion H+.

(c)

Interpretation Introduction

Interpretation:

Bronsted acid and base on the left and their conjugate partners on the right has to be identified.

[Al(H2O)6]3+(aq) + OH- (aq) [Al(H2O)5OH]2+(aq) + H2O (l)

Concept Introduction:

Bronsted –Lowry definitions:

A Bronsted –Lowry acid is a proton donor, it donates a hydrogen ion, H+
