StellarWeak Acids and Bases
Similar to other reactions, acid-base reactions have dynamic equilibria. The equilibrium constant for the first dissociation of an acid is known as , and the constant for a base is known as . Similar to all other equilibrium constants, these only change with temperature.
For a reaction, {HA + H_2O ⇆ A– + H_3O^+}
And for a reaction, {B + H_2O ⇆ BH+ + OH^–}:
For a reaction, {HA + H_2O ⇆ A– + H_3O^+}
Ka = ([A–][H3O+])/[HA]
Kb = ([BH+][OH–])/[B]
