Identify the Brønsted-Lowry acid and base in each reaction:

a. C 5 H 5 N + H 2  OH - + C 5 H 5 NH +

b. CH 3 COOH+H 2 O H 3 O + +C 2 H 3 O 2 -

c. KOH + HBr  H 2 O +KBr

Interpretation Introduction

Interpretation:

The Bronsted acid and base in the given reactions are to be determined.

Concept Introduction:

According to the Bronsted-Lowry theory, an acid is a substance which donates hydrogen ions (H+) and a base is a substance which accepts hydrogen ions (H+). Hence, a proton donor is called a Bronsted acid and a proton acceptor is called a Bronsted base.

Explanation of Solution

a) C5H5N+H2OOH+C5H5NH+

The given reaction is a Bronsted acid-base reaction. In an acid-base reaction, the transfer of protons takes place. According to the Bronsted acid-base theory, an acid is a proton donor and a base is a proton acceptor.

The reaction is as follows:

C5H5N+H2OOH+C5H5NH+base       acid

In this Bronsted acid-base reaction, H2O behaves as an acid because it is donating the protons and C5H5N behaves as a base as C5H5N is accepting the protons.

b) CH3CO2H+H2OH3O++CH3CO2
