one more thing to ask...what did u write as the other thing which lowers ur confidence of the concentration of FeCl3 and the rate.oxidation and reduction was already given so i wrote neutralisation reaction LOL athough i know its wrong.Does any one knows the correct answer for the name of this reaction????
for me, because the part was talking about thiosulfate ions, and how they reduce, so i thought about Fe3+ get reduced to Fe2+ by thiosulfate ions., donno whether rigtht or wrong. but it makes sense because the examiners said it in the same part, so obviously i have to use the fact that thiosulfate ions are reducing agents.

Well i didnt mention a name did it say so in the question to say a name i dont really remember.. but what i did write was that the thiosulfate ions will react with the iron(II) ions and that will affect our results and another person from my centre wrote exactly the same and we think it is correct.
