A Laboratory Procedure for the Reduction of Chromium(VI) to Chromium(III).
Lunn, George; Sansone, Eric B.
Journal of Chemical Education, v66 n5 p443-45 May 1989
Chromium(VI) compounds are classified as oxidizers and must be specially packaged and transported for disposal while Cr(III) compounds are considered nonoxidizers. A process which reduces Cr(VI) to Cr(III) by adding sodium metabisulfite followed by neutralization with magnesium hydroxide is explored. (MVL)
