Another chlorine conundrum
« on: 23/02/2006 11:21:09 »
If I react Iodine with sodium hypochlorite under alkaline conditions I get this reaction:
I2 + 7NaOCl + 6NaOH = 2Na3H2IO6 + 7NaCl + 2H2O

If I remove the sodium hydroxide I get chlorine why and what is the mechanism?
anybody any ideas

The reaction is: I2 + 2NaOH + 5NaClO  -->  2NaIO3 + 5NaCl + H2O.
You get chlorine simply from NaClO and NaCl when the solution is not alcaline: ClO- + Cl- + 2H+  -->  Cl2 + H2O
