    Does anyone know the ionic equation for the reaction between chlorine and sodium thiosulphate and how to work it out? I kind of get the idea but end up confusing myself!
    Thanks

    I will take a guess

    2S2O3 + Cl2 ---> 2Cl + S4O6

    May want to verify that : )

    thanks guys, just looked at the question again it says -
    Sodium thiosulphate reacts with chlorine to produce sulphate ions, chloride ions and hydrogen ions. Write a balanced ionic equation for the reaction between chlorine and sodium thiosulphate.

    just wonderin where the hydrogen ions fit into it? lol

    $

S_2O^{2-}_3+4Cl_2+5H_2O \longrightarrow 10H^++2SO^{2-}_4+8Cl^-

    you can get it from the half equations of the oxidation of thiosulphate to sulphate and reduction of chlorine to chloride

    This reaction would occour rather than the other one I guess is because Chlorine is a stronger oxidising agent than Iodine so can oxidise the thiosulphate
    $

S_2O^{2-}_3 + 5H_2O \longrightarrow 10H^++2SO^{2-}_4+8e^-

    $

Cl_2 + 2e^- \longrightarrow 2Cl^-

    Can some one confirm this reaction as the chemical reaction is not getting balanced like ionic reaction

    I find it difficult to balance the equation below:
    [img]file:///C:/Users/PLANTM~1.CHE/AppData/Local/Temp/msohtmlclip1/01/clip_image001.png[/img]Na2S2O3 + Cl2 + H2O Na2SO4 + NaCl + H2

    Can some one help me
