Answer to Problem 2.96QP

The chemical formula Mn3(PO4)3, of manganese (II) phosphate is incorrect.

Explanation of Solution

The oxidation state of manganese in manganese (II) phosphate is +2.

The oxidation state of phosphate ion atom is 3.

The oxidation state of manganese is assumed to be x.

The oxidation state of the metal center present in Mn3(PO4)3 is expressed as,

3x+3(3)=0x=93=+3

The calculated oxidation state of manganese is +3.

The given oxidation state and the calculated oxidation state is not same therefore, the chemical formula Mn3(PO4)3, of manganese (II) phosphate is incorrect.

(b)

Interpretation Introduction

To determine: The chemical formula NiBr2, of nickel (II) bromide is incorrect or not.

Interpretation: The chemical formula NiBr2, of nickel (II) bromide is incorrect or not is to be predicted.

Concept introduction: The naming of the compound is done on the basis of atoms attached to it and the charge present on each atom.

Answer to Problem 2.96QP

The chemical formula NiBr2, of nickel (II) bromide is correct.

Explanation of Solution

The oxidation state of nickel in nickel (II) bromide is +2.

The oxidation state of bromine atom is 1.

The oxidation state of nickel is assumed to be x.

The oxidation state of the metal center present in NiBr2 is expressed as,

x+2(1)=0x=+2

The calculated oxidation state of nickel is +2.

The given oxidation state and the calculated oxidation state is same therefore, the chemical formula NiBr2, of titanium (IV) bromide is correct.

(c)

Interpretation Introduction

To determine: The chemical formula Cr2S3, of chromium (III) sulfide is incorrect or not.

Interpretation: The chemical formula Cr2S3, of chromium (III) sulfide is incorrect or not is to be predicted.

Concept introduction: The naming of the compound is done on the basis of atoms attached to it and the charge present on each atom.

(c)

Answer to Problem 2.96QP

The chemical formula Cr2S3, of chromium (III) sulfide is correct.

Explanation of Solution

The oxidation state of chromium in chromium (III) sulfide is +3.

The oxidation state of sulfide ion is 2.

The oxidation state of chromium is assumed to be x.

The oxidation state of the metal center present in Cr2S3 is expressed as,

2x+3(2)=0x=62=+3

The calculated oxidation state of chromium is +3.

The given oxidation state and the calculated oxidation state is same therefore, the chemical formula Cr2S3, of chromium (III) sulfide is correct.

(d)

Interpretation Introduction

To determine: The chemical formula CuSO46H2O, of copper (II) sulfate hexahydrate is incorrect or not.

Interpretation: The chemical formula CuSO46H2O, of copper (II) sulfate hexahydrate is incorrect or not is to be predicted.

Concept introduction: The naming of the compound is done on the basis of atoms attached to it and the charge present on each atom.

Answer to Problem 2.96QP

The chemical formula CuSO46H2O, of copper (II) sulfate hexahydrate is correct.

Explanation of Solution

The oxidation state of copper in copper (II) sulfate hexahydrate is +2.

The oxidation state of sulfate ion is 2.

The oxidation state of copper is assumed to be x.

The oxidation state of the metal center present in CuSO46H2O is expressed as,

x+(2)=0x=+2

The calculated oxidation state of copper is +2.

The given oxidation state and calculated oxidation state is not same therefore, the chemical formula CuSO46H2O of copper (II) sulfate hexahydrate is correct.

Conclusion
  1. a. The chemical formula Mn3(PO4)3, of manganese (II) phosphate is incorrect.
  2. b. The chemical formula NiBr2, of nickel (II) bromide is correct.
  3. c. The chemical formula Cr2S3, of chromium (III) sulfide is correct.
  4. d. The chemical formula CuSO46H2O, of copper (II) sulfate hexahydrate is correct.
