Concept explainers
Interpretation:
The oxidation state is to be assigned to each given ion or element.
Concept information:
The oxidation state of a substance is defined as the transfer of electrons in a chemical compound. It can either be zero, positive or negative or as a charge which an atom of the element has in its ion or appears to have when present in the combined state with other atoms.
An atom which gains electron has a negative value of oxidation state and atom which loses has a positive oxidation state.
The oxidation state of an atom in Free State is zero.
The oxidation state of a monatomic ion is equal to the charge on the ion.

- Chromium has been investigated as a coating for steel cans. The thickness of the chromium film is determined by dissolving a sample of a can in acid and oxidizing the resulting Cr3+ to Cr2O72 with the peroxydisulfate ion: S2O82(aq) + Cr3+(aq) + H2O(l) Cr2O72(aq) + SO42(aq) + H+(aq) (Unbalanced) After removal of unreacted S2O82 an excess of ferrous ammonium sulfate [Fe(NH4)2(SO4)26H2O] is added, reacting with Cr2O72 produced from the first reaction. The unreacted Fe2+ from the excess ferrous ammonium sulfate is titrated with a separate K2Cr2O7 solution. The reaction is: H+(aq) + Fe2+(aq) + Cr2O72(aq) Fe3+(aq) + Cr3+(aq) + H2O(l) (Unbalanced) a. Write balanced chemical equations for the two reactions. b. In one analysis, a 40.0-cm2 sample of a chromium-plated can was treated according to this procedure. After dissolution and removal of excess S2O82, 3.000 g of Fe(NH4)2(SO4)26H2O was added. It took 8.58 mL of 0.0520 M K2Cr2O7 solution to completely react with the excess Fe2+. Calculate the thickness of the chromium film on the can. (The density of chromium is 7.19 g/cm3)arrow_forwardBalance each of the following equations according to the half-reaction method: (a) Sn2+(aq)+Cu2+(aq)S4+(aq)+Cu+(aq) (b) H2S(g)+Hg22+(aq)Hg(l)+S(s)(inacid) (c) CN(aq)+ClO2(aq)CNO(aq)+Cl(aq)(inacid) (d) Fe2+(aq)+Ce4+(aq)Fe3+(aq)+Ce3+(aq) (e) HBrO(aq)Br(aq)+O2(g)(inacid)arrow_forward
