Chapter 10: Problem 2

Give two examples of Arrhenius bases.

Short Answer

Expert verified
NaOH and KOH are examples of Arrhenius bases.

Step by step solution

01

Understanding Arrhenius Bases

An Arrhenius base is a substance that increases the concentration of hydroxide ions ( ext{OH}^-) when dissolved in water. This is the foundational definition from the Arrhenius theory of acids and bases.
02

Example 1: Sodium Hydroxide

Sodium hydroxide (NaOH) is a classic Arrhenius base. When dissolved in water, it dissociates into sodium ions ( ext{Na}^+) and hydroxide ions ( ext{OH}^-), increasing the concentration of ext{OH}^- ions in the solution.
03

Example 2: Potassium Hydroxide

Potassium hydroxide (KOH) is another Arrhenius base. Similar to NaOH, when KOH dissolves in water, it dissociates into potassium ions ( ext{K}^+) and hydroxide ions ( ext{OH}^-), thus increasing the number of ext{OH}^- ions in the solution.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Hydroxide Ions
Hydroxide ions, often symbolized as \( \text{OH}^- \), are negatively charged ions that consist of one oxygen atom and one hydrogen atom connected through a covalent bond. These ions play a critical role in determining the alkalinity of a solution. When compounds known as Arrhenius bases dissolve in water, they release hydroxide ions into the solution.
  • The presence of hydroxide ions in water is what gives a substance its basic properties.
  • The more hydroxide ions present, the stronger the base becomes.
Arrhenius bases, such as sodium hydroxide and potassium hydroxide, demonstrate this concept by increasing the concentration of \( \text{OH}^- \) ions in water, resulting in an alkaline or basic environment.
Sodium Hydroxide
Sodium hydroxide, with the chemical formula \( \text{NaOH} \), is one of the most common examples of an Arrhenius base. When \( \text{NaOH} \) dissolves in water, it dissociates into sodium ions \( \text{Na}^+ \) and hydroxide ions \( \text{OH}^- \). This dissociation is what increases the concentration of hydroxide ions in the solution, making it basic.
  • It is commonly used in industry for making soaps and detergents
  • Known for having a strong, caustic nature and is sometimes called "caustic soda."
The introduction of \( \text{OH}^- \) ions into the solution neutralizes acids and raises the pH level, reflecting the characteristics of a strong base.
Potassium Hydroxide
Potassium hydroxide, often represented by \( \text{KOH} \), is another well-known Arrhenius base. Like sodium hydroxide, potassium hydroxide also increases the concentration of hydroxide ions when it dissolves in water. Upon dissolving, \( \text{KOH} \) separates into potassium ions \( \text{K}^+ \) and hydroxide ions \( \text{OH}^- \).
  • Potassium hydroxide is used in the production of biodiesel and soap as well.
  • Known for being a strong base, it is utilized in various chemical synthesis processes.
This dissociation reinforces the basicity of the solution, further illustrating the concept of Arrhenius bases, which revolve around the release of \( \text{OH}^- \) ions.
