WebIn 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. Saturated solutions [ edit] WebAn aqueous solution of barium hydroxide is standardized by titration with a 0.122 M solution of perchloric acid.
