What is the Arrhenius definition of an acid?

A. A substance that increases [tex]H_3O^+[/tex] concentration when it is dissolved in water.
B. A substance that increases [tex]OH^-[/tex] concentration when it is dissolved in water.
C. A compound that donates protons.
D. A compound that accepts protons.



Answer :

Final answer:

An Arrhenius acid increases H3O+ ions in water, and a base increases OH- ions. Acids release H+ ions combining with water to form H3O+.


Explanation:

Arrhenius Definition of Acids and Bases: An Arrhenius acid is a compound that increases the concentration of H3O+ ions in water, while an Arrhenius base increases the concentration of OH- ions. When acids are dissolved in water, they release H+ ions which then combine with water to form H3O+, known as the hydronium ion.
