Chapter 16.1, Problem 4RC

Interpretation Introduction

Interpretation:

The correct conjugated acid and base part should be identified given the three different reactions.

Concept introduction:

An acid was defined as a substance whose turns blue litmus to red, water solution tastes sour and neutralizes the bases.

A base was defined as a substance whose turns red litmus to blue, aqueous solution tasted bitter and neutralizes acids.

Bronsted –Lowry conjugate acid-Base pairs:

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