Ammonium Hydroxide - Basicity of Ammonia in Water

Basicity of Ammonia in Water

In aqueous solution, ammonia deprotonates a small fraction of the water to give ammonium and hydroxide according to the following equilibrium:

NH3 + H2O NH4+ + OH−.

In a 1M ammonia solution, about 0.42% of the ammonia is converted to ammonium, equivalent to a pH of 11.63. The base ionization constant is

Kb = / = 1.8×10−5

Famous quotes containing the word water:

    “We wished our two souls
    might return like gulls
    to the rock. In the end,
    the water was too cold for us.”
