Capitolo 16, Problema 33c
Identify each substance as an acid or a base and write a chemical equation showing how it is an acid or a base according to the Arrhenius definition. c. KOH(aq)
Guida verificata passo dopo passo1
Identify the substance: KOH is potassium hydroxide.
Recall the Arrhenius definition: An Arrhenius base is a substance that increases the concentration of hydroxide ions (OH⁻) in aqueous solution.
Determine if KOH fits the definition: KOH dissociates in water to produce K⁺ and OH⁻ ions.
Write the dissociation equation: KOH(aq) → K⁺(aq) + OH⁻(aq).
Conclude that KOH is an Arrhenius base because it increases the concentration of OH⁻ ions in solution.

Arrhenius Definition of Acids and Bases
The Arrhenius definition states that acids are substances that increase the concentration of hydrogen ions (H⁺) in aqueous solution, while bases increase the concentration of hydroxide ions (OH⁻). This definition is fundamental for classifying substances based on their behavior in water.

Arrhenius Acids and Bases
Chemical Equations
Chemical equations represent the transformation of reactants into products, showing the reactants' identities and their quantities. In the context of acids and bases, these equations illustrate how an acid donates H⁺ ions or how a base provides OH⁻ ions in solution, which is essential for demonstrating their properties.

KOH as a Base
Potassium hydroxide (KOH) is classified as a strong base according to the Arrhenius definition because it dissociates completely in water to produce K⁺ and OH⁻ ions. The chemical equation for this dissociation is KOH(aq) → K⁺(aq) + OH⁻(aq), highlighting its role in increasing hydroxide ion concentration in solution.
