Io3- to i- half equation
Web26 okt. 2024 · Home > Community > How can I balance the disproportionation redox reaction of triiodide (I3-) into iodide (I-) and iodate (Io3-), considering that triiodide has an oxidation number of - 1/3.? Web20 nov. 2005 · This one is a bit tricky. Like always, first split it up into two distinct half-reactions: IO3- --> I2 I- --> I2 and then balance the I atoms: 2IO3- --> I2 2I- --> I2 Continue from here and I think you should be able to get it. Tell me if you have problems.
