Ionic Equation?

What is an ionic equation?
(Practice Exam Q's on titrations, Question 4)
It says 'sodium thiosulphate' but there's no 'Na' in the equation!!

An equation only showing the ions that are reacting.

hi!
that means Na is a spectator ion and therefore doesnt want to participate with the others
erm...
if it makes it easier just imagine it in there as Na+ and just cross it out...
:)
i hope that is ok...
my chem is a little rusty...
