Holy crap this was my high school chemistry teacher

[@alternative_piccolo3130]

I'm confused, if Fe2+ and Fe3+ are mixed, they make prussian blue. Why is it that when she added Fe2+ in the cyanide complex to the test tube with Fe2+ ions it turned blue? Does the iron get oxidized? Thank you.

Is this why blood can be red or blue?

[@alternative_piccolo3130]

No, your blood is never blue. If your blood were to do this, that would mean there's cyanide in it.

@Digitalni Podaci wow

[@scotkaufman7094]

it is iron hexacyanoferrate not iron ferrocyanide
