How do I write oxidation and reduction equations for IO₃⁻ and I⁻ forming I₂?

[jen24007]

hey guys! i am lost with my current unit...redox reactions. i was wondering if any chem whizzes could lead me in the right direction as how to write the oxidation and reduction equations for the following reaction:

IO-3 (aq) + I- (aq)--> I2 (aq)

Any help would be greatly appreciated! I still have no idea why i took AP chem...

First of all the equation isn't complete. What happened to the oxygen atom? In general you should first determine the oxidation state of each element in the reaction, there are rules which can be applied to help you do this, can you remember them?

Hoot : The problem requires you to complete the equation.

jen : There must be examples in your text showing you exactly how to go about this process.

Here's another detailed example : http://www.mpcfaculty.net/mark_bishop/redox_balance_half_acid_example.htm

This counts as coursework, and hence must follow the relevant posting rules.

Oo right, makes sense now.
