Main Question or Discussion Point

Hi everyone.

I don't have access to a visible spectrophotometer to do this so I'm looking for results on the internet.

I just did the persulfate variation of the iodine clock and I need absorbance spectroscopy results for the blue/black complex that is formed with the iodine and starch at the end. I know the wavelength of the spectrophotometer should be set at 570nm (yellow orange colour) as this is the complementary colour of purple. This is all I know though.

Anyone know where I might find results for this?

Cheers.
