quantitative measurement of oxidant
Whats the most accessible way to quantitatively measure the amount of oxidant (either H2O2 or CH3CO3H, or sodium percarbonate) in a solution?

Just offhand I would think that titrating with a standard sodium thiosulfate solution would be the easiest.

I think I've seen a procedure for determining concentration of hydrogen peroxide with standardized potassium permanganate. But isn't there a risk that
Mn<sup>2+</sup> could catalyze decomposition of the H<sub>2</sub>O<sub>2</sub>?

Magpie, is there any way to visualize the endpoint without starch and iodine?

I don't know if there is any other easy way. It could probably be done potentiometrically, but that takes special equipment I guess.
