WebKa from Molarity We can use molarity to determine the Ka value. Consider dissociation of acid HX, HX ⥦ H + + X – By definition, we can quantify the Ka formula as a product divided by the reactant of the reaction. Ka = [Product] / [Reactant] We can fill the concentrations to write the Ka equation based on the above reaction.
