The solution shown in the picture holds pure water at 298 K with a pH = 7.0 You are asked to make a solution with the highest possible ion concentration without changing the pH. Drag all the ions you can into the soltion to increase the ion concentration without changing the pH of the solution. Alkalia metal cations (Na+, K+...) and Alkali Earth Cations (Mg2+,Ca2+...) are negligibly weak acids. Strong bases:K2O, Na3N, NaOH, NaH
