The pH of the solution depends on the concentration of ammonium hydroxide, temperature, etc. I happen to think its about 11.5 Dude, yer wrong - its 11.6 definitely pH = -log[H3O+] = 5.13. Comments: We're given Kb for ammonia, but it is ammonium ion which is reacting with water. Ammonium ion is acting as an acid and donating a proton to water. Therefore, we need the Ka of ammonium ion. Ammonia is the conjugate base of ammonium ion. The product of the Ka of an acid, and the Kb of the conjugate base is Kw. Structure, properties, spectra, suppliers and links for: Ammonium vanadate, 7803-55-6, 11115-67-6 Acidic salts, such as AMMONIUM MOLYBDATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases The answer is Ka of ammonium is same as Kb of acetate [5.6 * 10^-10] so that both will be equal strength as pH 7.0. How is this obtained? (work needed) And What would the pH be if the concentration were 0.1 M in ammonium acetate? 0.4M? Thanks!!

To prevent medium pH from rapidly changing, we should keep an appropriate Ammonium/Nitrate ratio, according to the cultivar, temperature and the growing stage. It is noteworthy that under certain conditions, the pH may not respond as expected due to nitrification (conversion of Ammonium into Nitrate by bacteria in the soil)

As the ammonium-N in fertilizers undergoes nitrification (conversion of ammonium to nitrate in soils by bacteria), hydrogen (H +) is released, which can increase acidity. As the percentage of ammonium increases in a given fertilizer the acidifying potential will also be increased, thus reducing pH An Ammonium Ion Selective Electrode sensor specifically designed to measure 0.1ppm to 18,000 ppm (5x10-6M to 1M) concentrations of Ammonium.
