I don't think I could LIVE in an environment that WOULD oxidize Cr^3 to Cr^6. You can find more than you want to know about chromium chemistry and biochemistry at: http://64.233.183.104/search?q=cache:7WcVuGjRZIwJ:www.nature.nps.gov/haz ardssafety/toxic/chromium.pdf+oxidized+Cr3%2B+to+Cr6%2B&hl=en But it is silent on the oxidation issue. IIRC, oxidizing agents as strong as Mn(VII)/permanganate, or stronger, are required. -- Regards, John Woodgate, OOO - Own Opinions Only. The good news is that nothing is compulsory.
