Different types of bases

There are also different types of bases, maybe weak, maybe strong:
  1. Organic molecules
    You can think of amines, and of amino acids (see module 11)

  2. Negative ions
    In principle, all negative ions can receive, capture H+ ions. So they are always bases, strong or weak.

  3. some positive ions
    Those cations, after having donated H+, can take back that H+ ion and thus act as a base.

  4. Some neutral molecules; more hereover later.

More information about acids and bases can be found in module 9.
