How Do You Spell ARRHENIUS BASE?

Pronunciation: [ɐrhˈiːnɪəs bˈe͡ɪs] (IPA)

Arrhenius base is a term used in chemistry to describe a substance that produces hydroxide ions in aqueous solutions. The word is spelled as /əˈrɛniəs beɪs/ in IPA phonetic transcription to reflect the correct pronunciation. The first syllable is pronounced with a schwa sound, followed by the stressed second syllable pronounced as "ren-ee-us." The final two syllables are pronounced as "bay-ss." This term is named after the Swedish chemist Svante Arrhenius, who first proposed the concept of acids and bases in 1884.

ARRHENIUS BASE Meaning and Definition

  1. An Arrhenius base is a compound that, when dissolved in water, produces hydroxide ions (OH-) as the predominant species. This definition is based on the concept proposed by Swedish chemist Svante Arrhenius in the late 19th century. Arrhenius bases are sometimes referred to as alkali bases, as they typically exhibit alkaline properties.

    In order for a substance to be classified as an Arrhenius base, it must meet certain criteria. Firstly, it needs to be a compound that is capable of dissociating or ionizing in water. This dissociation or ionization process involves the release of hydroxide ions. Secondly, the concentration of the hydroxide ions in water should be relatively high.

    Arrhenius bases have a unique property of neutralizing acids. When combined with an acid, they form water and a salt through a chemical reaction known as neutralization. This reaction occurs due to the capability of Arrhenius bases to accept protons (H+) from acids.

    Common examples of Arrhenius bases include sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium hydroxide (Ca(OH)2). These compounds are known for their strong alkaline properties, high degree of solubility in water, and ability to dissociate into hydroxide ions.

    In summary, an Arrhenius base is a compound that, when dissolved in water, produces hydroxide ions as the main species, can neutralize acids through a neutralization reaction, and is capable of dissociating or ionizing in water.

Etymology of ARRHENIUS BASE

The term "Arrhenius base" is derived from the name of Svante Arrhenius, a Swedish chemist and physicist, who introduced the concept of acids and bases in 1884. Arrhenius proposed that substances that dissolve in water to produce hydroxide ions (OH-) are bases, while those that produce hydrogen ions (H+) are acids. This groundbreaking theory forms the basis of what we now call the Arrhenius theory of acids and bases.
