solutions and ions
Cations and anions
There are two different kinds of ions:
The cations are ions which have one or more positive electrical charges.
The anions are ions that have one or more negative electric charges.
is electrically neutral if it has as many positive electrical charges
as negative electrical charges.
solutions are neutral:
- The molecular aqueous solutions (where the solute is composed of
molecules) are neutral because it contains molecules that are
- Aqueous ionic solutions (whose solute consists of ions) are neutral
because positive charges carried by cations are compensated by the
negative charges carried by the anions.
neutrality of an ionic solution implies that the cations are always
accompanied by anions and inversely.
