Consider a solution of monoprotic weak acid having dissociation constant K_(a) . What is the minimum concentration C in terms of K_(a) , such that the concentration of the undissociated acid that the concentration of the undissociated acid can be equated to C within a 10% limit of error ? Assume that activity coefficient correction are negligible.
