Summary:
- A base can be defined as a substance, which accepts a hydrogen ion from another substance.
- A strong base is a base, which ionizes completely in an aqueous solution.
- Weak bases are a base that ionizes only slightly in a solution of water.
- A base ionization constant is the equilibrium constant for the ionization of a base.
- For ammonia the expression is: For ammonia, the equilibrium greatly favors the reactants and the extent of ionization is very small.
- The numerical value of is a reflection of the strength of the base.
