Answer to Problem 3.68AP

The formula of the ionic compound formed when Fe3+ reacts with CN- is Fe(CN)3.

Explanation of Solution

When iron (III) cation (Fe3+) reacts with cyanide ion (CN-), the compound formed is iron (III) cyanide (Fe(CN)3.)

  Fe3++CN-Fe(CN)3

The charges are not equal in magnitude, three cyanide ions are required to balance the charge.

The formula of the ionic compound formed when Fe3+ reacts with CN- is Fe(CN)3.

(b)

Interpretation Introduction

Interpretation:

The formula of the ionic compound formed when Fe3+ reacts with PO43- has to be given.

(b)

Expert Solution

Answer to Problem 3.68AP

The formula of the ionic compound formed when Fe3+ reacts with PO43- is FePO4.

Explanation of Solution

When iron (III) cation (Fe3+) reacts with phosphate ion (PO43-), the compound formed is iron (III) phosphate (FePO4).

  Fe3++PO43-FePO4

The charges are equal in magnitude, and one of each ion is needed to balance the charge.

The formula of the ionic compound formed when Fe3+ reacts with PO43- is FePO4.

(c)

Interpretation Introduction

Interpretation:

The formula of the ionic compound formed when Fe3+ reacts with HPO42- has to be given.

Answer to Problem 3.68AP

The formula of the ionic compound formed when Fe3+ reacts with HPO42- is Fe2(HPO4)3.

Explanation of Solution

When iron (III) cation (Fe3+) reacts with hydrogen phosphate ion (HPO42-), the compound formed is iron (III) hydrogen phosphate (Fe2(HPO4)3).

  Fe3++HPO42-Fe2(HPO4)3

The charges are not equal in magnitude, three hydrogen phosphate ions and two iron ions are required to balance the charge.

The formula of the ionic compound formed when Fe3+ reacts with HPO42- is Fe2(HPO4)3.

(d)

Interpretation Introduction

Interpretation:

The formula of the ionic compound formed when Fe3+ reacts with H2PO4- has to be given.

Answer to Problem 3.68AP

The formula of the ionic compound formed when Fe3+ reacts with H2PO4- is Fe(H2PO4)3.

Explanation of Solution

When iron (III) cation (Fe3+) reacts with dihydrogen phosphate ion (H2PO4-), the compound formed is iron (III) dihydrogen phosphate (Fe(H2PO4)3).

  Fe3++H2PO4-Fe(H2PO4)3

The charges are not equal in magnitude, three dihydrogen phosphate ions are required to balance the charge.

The formula of the ionic compound formed when Fe3+ reacts with H2PO4- is Fe(H2PO4)3.
