Dichromate oxidation number
WebOxidation number method is based on the difference in oxidation number of oxidizing agent and the reducing agent. Half-reaction method depends on the division of the redox reactions into oxidation half and reduction half. ... For instance, a reaction is given where Fe 2+ ions are converted to Fe 3+ ions by dichromate ions in an acidic solution. http://ch302.cm.utexas.edu/worksheets/basic-redox-wkst-KEY.pdf
