2.A 1,000 L water tank contains 1,200 moles of an experimental chemical that is a weak acid with pka of 7.2. The PH of the tank is 9.0. what is molar concentration of the chemical that will dissolve in the water at PH 9.0? Assume the basic form of the chemical is miscible and the water solubility of the acidic form is negligible.
