**DrBob222**, Wednesday, July 13, 2011 at 11:36amI think it may be because it is relatively easy to reduce metals/unknowns to their lower/lowest stable state, then oxidize them, than it is to oxidize them to a higher/highest stable state and reduce them. A second reason may be that standard solutions of oxidants generally are more stable than standard solution of reductants (true for cerium solutions but not for permanganate solutions). Then again, I may on the wrong wavelength.
