pH and Acidity of Ammonium Chloride (NH4Cl) Aqueous Solution
WebAmmonia NH3 reacts with water: NH3 + H2O = NH4+ + OH- ; so in effect ammonium hydroxide is 100% ionized, there is just not very much of it. So the question is: What is the … In a 1 M ammonia solution, about 0.42% of the ammonia is converted to ammonium, equivalent to pH = 11.63 because [ NH+ 4 ] = 0.0042 M, [OH − ] = 0.0042 M, [NH 3 ] = 0.9958 M, and pH = 14 + log 10 [OH − ] = 11.62. The base ionization constant is Kb = [ NH+ 4 ] [OH −] [NH 3] = 1.77 × 10 −5.
