Chapter 9, Problem 9.66AP

a.

Summary Introduction

To determine:

The anion formed from the given hydrosulfuric acid $\left({\text{H}}_{\text{2}}\text{S}\right)$.

Introduction:

According to Bronsted-Lowry concept, an acid is a species that can easily donate a proton and the species that accepts this donated proton is known as a base. The species that is left after the donation of a proton is an anion and is known as a conjugate base while the species that gains the proton acts as a cation and is known as a conjugate acid.

b.

Summary Introduction

To determine:

The anion formed from the given lactic acid $\left({\text{CH}}_{\text{3}}\text{CH}\left(\text{OH}\right)\text{COOH}\right)$.

Introduction:

According to Bronsted-Lowry concept, an acid is a species that can easily donate a proton and the species that accepts this donated proton is known as a base.
