3. Determine the shape: The dichromate ion has a structure that can be visualized as two tetrahedral units sharing one oxygen atom.4. Assign formal charges: Each chromium atom is in the +6 oxidation state, and the overall charge of the ion is -2.5. Draw the structure: Place the two ...

Since the molecule consists of ammonium ion, a reducing agent, and of chromium in the +6 oxidation state, an oxidizing agent, it is explosively unstable. Decomposition is exothermic; and once initiated it continues spontaneously until the entire quantity is decomposed-sometimes called a "chromate ...
What is the oxidation state of Pb in PbO_{2}? What is the oxidation number of Cr in K_2CrO_4? What is the oxidation number of magnesium in the compound Mg(OH)2? What is the balanced equation for the oxidation of the iron(II) ion by permanganate?

The reaction mechanism is discussed in the general context of nucleophilic attack on dichromate ion. A comparison of this rate constant with those for the analogous reaction using different nucleophiles indicates that it is polarizability rather than basicity which determines nucleophilic reactivity towards...
Thus, the potassium permanganate preparation involves a reaction of MnO2with KOH to produce MnO2−4followed by electrolytic oxidation of manganate to produce permanganate ion, MnO2−4. After this manganese ion, the salt will be oxidized by peroxodisulphate to permanganate ion according to the re...
