All you Year 12 (or some smart Year 11) folks can help me out here:
An experiment that our class conducted was decomposition of silver halides.
One of the discussion questions was: "Why was the filter paper washed with the sodium thiosulfate solution? Write an equation for this reaction."
The equation part is what I'm stuck on. Given that the formula of sodium thiosulfate is Na2-S2-O3 and one of the products of the reaction is Ag(S2-O2)2^-3 (i.e. charge of -3?) can somebody help me write a BALANCED equation of sodium thiosulfate with silver chloride (or silver iodide)? Please make a quick reply because I need it before the end of Tuesday (tomorrow).
By the way I suspect that the product of the reaction given is wrong (Ag(S2-O2)2^-3), so if it is wrong please point that out and correct it please.
