Title: Balance Equation
Post by: cynthia on March 11, 2006, 09:11:03 PM

How do I balance and write the cell notation for an electrochemical cell?

S2O3 2- + I2 > I- + S4O6 2-

Thank you,

Cynthia

Simple redox reaction!
 
I₂ + 2e^- -----> 2 I^-
2 S₂O₃^2- -----> S₄O₆^2- + 2e^-

Just put this two half-reactions together
