Question
Chapter 5, Problem 5.80E
Interpretation Introduction

Interpretation:

The option corresponding to the correct oxidation number of sulfur in the ion SO42 is to be identified.

Concept Introduction:

The oxidation state or number in a compound is the charge present on the individual atom if all the bonds are assumed to be ionic. The oxidation number is assigned by the following set of rules:

1. The oxidation number present on a neutral compound is always zero.

2. The oxidation number of atoms present in an element in the pure form is zero.

3. In the compounds, if halogens are present the oxidation number of halogens is 1, but when oxygen is present with them they have different oxidation number.

4. The oxidation numbers of Group 1 metals are always +1 and Group 2 metals are always +2.

5. The common oxidation number of oxygen in most compounds is 2 and oxidation number of hydrogen is +1.

    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)
