A- is a weaker base than OH-, and the equilibrium will lie to the left. The solution of a strong acid will have extremely few to no undissociated HA molecules. So one way to find out the acid and base is to exchange the ions between the salt and water. In both cases the equilibrium favors the dissociation products, and water is said to exert a effect on any strong acid or base. match each acid with the species that is/are present in the greatest concentration in the final solution. 3. Usually only the first dissociation is taken into account in calculations involving polyprotic acids. 4) Is the solution of CH3NH3CN acidic, basic or neutral. .Salts are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge).
