Definition: An Arrhenius base is a substance that when added to water increases the number of OH-ions in the water.Arrhenius bases follow the reaction:efinition: An Arrhenius base is a substance that when added to water increases the number of OH-ions in the water.
The acid dissociation constant is less for weak acids compared to strong acids. Arrhenius acid-base theory is the most restrictive theory reqiring the compound to have an H + or OH-and to be soluble in water.The list of Arrhenius acids is given below: When Arrhenius acids are in pure state they are covalent compounds; that is, they do not contain H + ions.he acid dissociation constant is less for weak acids compared to strong acids. Arrhenius acid-base theory is the most restrictive theory reqiring the compound to have an H + or OH-and to be soluble in water.
