So I need to find the concentration of I2(aq)
The reactions are;
2I-(aq)+S2O82--->2SO42-+I2(aq)
2S2O32-(aq)+I2(aq)-->S4O62-(aq)+2I-(aq)
The concentration for KI is 0.0401 mol/L, for(NH4)2S2O8 is 0.0602mol/L and for Na2S2O3 is4.17x10-4mol/L.
4.04 mL of KI, 4.04 mL of(NH4)2S2O8, 2.01 mL ofNa2S2O3 are used
I know I should be using the second equation, I find the molesfor I2 but I cannot figure the concentration
