2Fe(3+) + 2S2O3(2-) = 2Fe(2+) +S4O6(2-)

2Fe(3+) + 2S2O3(2-) = 2Fe(2+) +S4O6(2-)
What's the overall reaction though instead of just the reduction?

Is this the correct equation for the reaction between sodium thiosulfate and iron (III) nitrate?
2 Na2S2O3(aq) + 2 Fe(NO3)3(aq) ----> Na2S4O6(aq) + 2 Fe(NO3)2(aq) + 2 NaNO3(aq)

But this is still not the overall reaction....

It'll do ...

Although, in reality you will just be left with a solution containing lots of positive and negative ions. you can't really say that the iron(III) ions will specifically go with the nitrate ions etc..

2Fe3+ + 2S2O32- --> 2Fe2+ + S4O62-

What will the equation look like then?

2Fe3+(aq) + 2S2O32- --> 2Fe2+(aq) + S4O62-(aq)
This equation doesn't account for the sodium and nitrate ions...

Mine was for the complete reduction of Fe3+.

In all honesty, I had an educated guess, so.

In any case, it doesn't balance. You have 3- on the LHS and 6- on the RHS.

Like I said, you can't really ascribe ions as they are all spectator ions in solution, so it doesn't make sense trying to.

You should never include spectator ions specifically for this reason - they are spectator ions and not involved.
