What is Arrhenius Theory?

Arrhenius theory was introduced by a Swedish chemist Svante Arrhenius in 1884. This theory takes into account how acids and bases dissociate in water to explain their behaviour in aqueous solutions.

According to this theory, the substances dissociate in water to produce electrically charged atoms called ions, which are either hydrogen ions or hydroxide ions in general.

Arrhenius Theory

Arrhenius Theory introduced in 1887 by Swedish scientist Svante Arrhenius, is used to describe the behavior of acids and bases in aqueous solutions. This theory states that a material that releases hydroxide ions (OH) in water is an Arrhenius base, and a substance that releases hydrogen ions (H+) in water is an Arrhenius acid.

This article will thoroughly explain the Arrhenius theory, along with instances of Arrhenius bases, Arrhenius acids and Arrhenius theory of electrolytic dissociation.

Arrhenius Theory of Acid and Base

Arrhenius theory particularly focus on the acidic or basic behavior of a substance. As per this theory, the substances that dissociate in water to release hydrogen ions (H+) are called acids, whereas the substances that dissociate in water to release hydroxide ions (OH–) are called bases....

Reaction Between Arrhenius Acid and Base

A neutralization reaction occurs when an Arrhenius acid and an Arrhenius base interact. The hydroxide ions (OH−) from the base and the hydrogen ions (H+) from the acid which mix to generate water in a neutralization process. Furthermore, the negative ion from the acid and the positive ion from the base combine to create a salt....

Arrhenius Theory of Electrolytic Dissociation

Arrhenius Theory of Electrolytic dissociation states that the aqueous solution of acid conducts electricity when a substance called electrolyte is dissolved in the solution, which further dissociates into ions and conducts electricity....
