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...
