Calcium hydroxide is an Arrhenius base. You can see that it consists of a cation (we know calcium should be a cation because it is a metal on the left side of the periodic table bonded to elements on the right side). The anions are hydroxyl groups. #Ca(OH)_2->Ca^(2+)+2OH^-#.
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.
