Key Concepts

Acid-Base Theory (Arrhenius Model)

The Arrhenius model of acid-base theory is a fundamental concept in chemistry that classifies acids and bases based on their ion production in water. According to this model, acids are substances that produce hydrogen ions (H+) in aqueous solution, while bases produce hydroxide ions (OH–). This historical framework lays the groundwork for understanding chemical reactions in aqueous environments and has influenced the development of more comprehensive acid-base theories.

Arrhenius Base

An Arrhenius base is defined as a substance that increases the concentration of hydroxide ions (OH–) when dissolved in water. This definition highlights the nature of bases in aqueous solutions, marking a substance as a base based solely on its ability to release OH– ions in water.
