Ahh, Svante Arrhenius. Cool guy. Wish I'd met him.
Anyway, Arrhenius created a definition for an acid and for a base --
Acid - a substance which produces hydronium ions (H3O+) in aqueous solution
Base - a substance which produces hydroxide ions (OH-) in aqueous solution
That's it!
Svante Arrhenius
An Arrhenius acid increases [H+] in the solution.
Salt and water are formed from the neutralization of an Arrhenius acid with an Arrhenius base.
An Arrhenius acid increases [H+] in the solution.
An Arrhenius base produces OH- ions.
An Arrhenius acid-base reaction is characterized by the formation of water and a salt when an Arrhenius acid, which produces hydrogen ions (H⁺) in water, reacts with an Arrhenius base, which produces hydroxide ions (OH⁻). The reaction typically involves the neutralization of these ions, resulting in the formation of water (H₂O) and an ionic compound. This concept is fundamental in acid-base chemistry and illustrates the behavior of acids and bases in aqueous solutions.
No, HI (hydroiodic acid) is not considered an Arrhenius acid because it does not dissociate in water to release H+ ions as defined by the Arrhenius theory.
The concept of acids has been understood for centuries, but the modern understanding and characterization of acids as substances that donate hydrogen ions was developed in the late 19th century by Swedish chemist Svante Arrhenius.
a strong arrhenius acid is more highly ionized while the weak acid isn't The greater the degree of ionization of an acid, the better its water solution will conduct a current. Hydrochloric, sulfuric, and nitric acids ionize almost comploetely and thus are strong acids. Acetic acid and hydrosulfuric acid ionize only slightly and thus are weak acids.

HI
Swedish chemists Jöns Jacob Berzelius and Svante Arrhenius were among the first to describe bases in this manner in the early 19th and 20th centuries, respectively. They established the concept that bases are compounds that accept protons (H+ ions) in chemical reactions, forming salts.
Hydrofluoric acid is the Arrhenius acid that contains the fluoride anion.
