4. (22) Pure liquid ammonia solution is known as ammonium hydroxide (NH4OH). Upon dissolving in water, the following dissociation reactions occur: NH4OH à NH3 + H2O NH, + H+ Bà NH4 Kg = 109.26 If 0.25 mg of NH4OH is added to 1 L of pure water, what will be the final pH? Note: assume the first reaction proceeds irreversibly to completion, and do not neglect the contribution of water dissociation to the pH. Assume no exchange of NH3 with the atmosphere occurs.
