Chapter 2: Q. 2.55 (page 87)

a. What is the conjugate acid of A?

b. What is the conjugate base of A?

Short Answer

Expert verified

The compound generated when an acid has contributed its proton is referred to as a conjugate acid.For example, H3O+ is regarded as the conjugate acid of H2O.

Step by step solution

01

Conjugate acid

The compound generated when an acid has contributed its proton is referred to as a conjugate acid.For example, H3O+ is regarded as the conjugate acid of H2O.

02

Conjugate base

The compound generated when abase has acquired a proton is referred to as a conjugate base. For example, F- ion is regarded as the conjugate base of HF.

03

Identifying the conjugate acid and base in the compound

a. The conjugate acid can be drawn by identifying the most basic site, followed by its protonation.

Identification of conjugate acid

b. The conjugate base can be drawn by identifying the most acidic site followed by removing a proton from the acidic site.
