Chapter 16, Problem 7RQ

Interpretation Introduction

Interpretation:

Stronger acids as well as weaker acids than acetic acid has to be determined.

Concept Introduction:

Arrhenius gave the broader picture and suggested that acids can release an excess of ${\text{H}}_3{\text{O}}^{+}$ ion on dissolution in the water while bases can release an excess of ${\text{OH}}^{-}$ ion on dissolution in water.

Bronsted-Lowry acid outlined the definition of acids that donate ${\text{H}}^{+}$ or a proton while bases that accept ${\text{H}}^{+}$ or a proton.

In accordance with Lewis concept, an acid species accepts an electron-pair from some other electron-rich species while a base that has generally more electron density donates it to another electron-deficient species.

Acids that have higher ${\text{K}}_{\text{a}}$ value in aqueous solution are referred to have higher acidic character.
