Chapter 20, Problem 113QRT

(a)

Interpretation Introduction

Interpretation:

Moles of ions that is present when 1.00mol of [Pt(en)Cl2] is dissolved in water has to be determined.

(a)

Expert Solution
Check Mark

Explanation of Solution

Given complex has formula of [Pt(en)Cl2].

The complex [Pt(en)Cl2] do not dissociate into ions in water.  This is because there are no counter ions present in it.  The complex dissolves in water but does not dissociate in water.  The equation can be given as shown below.

    [Pt(en)Cl2](s)[Pt(en)Cl2](aq)

Therefore, there are no ions in the solution of [Pt(en)Cl2].

(b)

Interpretation Introduction

Interpretation:

Moles of ions that is present when 1.00mol of Na[Cr(en)2(SO4)2] is dissolved in water has to be determined.

(b)

Expert Solution
Check Mark

Explanation of Solution

Given complex has formula of Na[Cr(en)2(SO4)2].

The complex Na[Cr(en)2(SO4)2] contains a complex anion and a counter cation.  Therefore, dissociation takes place in water.  The equation can be written as shown below.

    Na[Cr(en)2(SO4)2](s)[Cr(en)2(SO4)2](aq)+Na+(aq)

Therefore, there are two ions in the solution of Na[Cr(en)2(SO4)2].

(c)

Interpretation Introduction

Interpretation:

Moles of ions that is present when 1.00mol of K3[Au(CN)4] is dissolved in water has to be determined.

(c)

Expert Solution
Check Mark

Explanation of Solution

Given complex has formula of K3[Au(CN)4].

The complex K3[Au(CN)4] contains a complex anion and a counter cation.  Therefore, dissociation takes place in water.  The equation can be written as shown below.

    K3[Au(CN)4](s)[Au(CN)4]3(aq)+3K+(aq)

Therefore, there are four ions in the solution of K3[Au(CN)4].

(d)

Interpretation Introduction

Interpretation:

Moles of ions that is present when 1.00mol of [Ni(H2O)2(NH3)4]Cl2 is dissolved in water has to be determined.

(d)

Expert Solution
Check Mark

Explanation of Solution

Given complex has formula of [Ni(H2O)2(NH3)4]Cl2.

The complex [Ni(H2O)2(NH3)4]Cl2 contains a complex cation and a counter anion.  Therefore, dissociation takes place in water.  The equation can be written as shown below.

    [Ni(H2O)2(NH3)4]Cl2(s)[Ni(H2O)2(NH3)4]2+(aq)+2Cl(aq)

Therefore, there are three ions in the solution of [Ni(H2O)2(NH3)4]Cl2.
