Acids and Bases Definitions: Acids And Bases Section 5.1 Answer Key

Acids and bases are two important classes of chemical compounds that have distinct properties and play crucial roles in various chemical reactions. In this section, we will explore the different definitions of acids and bases proposed by Arrhenius, Bronsted-Lowry, and Lewis.

Arrhenius Definition

The Arrhenius definition of acids and bases was proposed by Svante Arrhenius in 1887. According to this definition:

• An acid is a substance that, when dissolved in water, produces hydrogen ions (H+).
• A base is a substance that, when dissolved in water, produces hydroxide ions (OH-).

Bronsted-Lowry Definition, Acids and bases section 5.1 answer key

The Bronsted-Lowry definition of acids and bases was proposed by Johannes Bronsted and Thomas Lowry in 1923. This definition focuses on the transfer of protons (H+) between molecules.

• An acid is a substance that can donate a proton (H+).
• A base is a substance that can accept a proton (H+).

Lewis Definition

The Lewis definition of acids and bases was proposed by Gilbert N. Lewis in 1923. This definition is more general than the previous two and focuses on the sharing of electron pairs.

• An acid is a substance that can accept an electron pair.
• A base is a substance that can donate an electron pair.

Frequently Asked Questions

What is the difference between a strong acid and a weak acid?

Strong acids dissociate completely in water, releasing all their hydrogen ions (H+). Weak acids, on the other hand, only partially dissociate, resulting in a lower concentration of H+ ions in solution.

How does a buffer solution maintain a stable pH?

A buffer solution contains a weak acid and its conjugate base or a weak base and its conjugate acid. When small amounts of acid or base are added to the solution, the buffer components react to neutralize the added ions, minimizing changes in pH.

What is the role of acids and bases in everyday life?

Acids and bases play crucial roles in numerous everyday applications, including food preservation, cleaning products, fertilizers, and pharmaceuticals. Their properties are harnessed to achieve specific effects, such as acidity in beverages, alkalinity in detergents, and neutralization in antacids.
