what's the equation for potassium iodide with potassium persulfate?

Question

I need both the complete chemical equation and the net ionic equation and i can't find either anywhere! Thanks!
K2S2O8 + KI.....???

Answer 1

Combine

(S2O8)2- + 2e- ----> 2(SO4)2-

and

2I- -----> I2 + 2e-

for your answer.

Answer 2

a sulphate is SO4 a persulphate is S2O8so the reaction must be: S2O8 + 2I ----> 2SO3 + 2IO already balanced as a redox. i never found something like this, maybe solphate+iodide=ipoiod+sulfite
