Chapter 19, Problem 19.89AP

(a)

Interpretation Introduction

Interpretation: The information regarding the production of elemental Magnesium metal by electrolysis of molten ${\text{Mg}}^{2+}$ salts that are present in the sea water is given. Various questions based on this electrolysis have to be answered.

Concept introduction: Electrolysis is the process that leads to the conversion of electrical energy into chemical energy.

To determine: The electrode at which the formation of elemental Magnesium metal occurs.

(b)

Interpretation Introduction

To determine: The need if required for the separation of principal ingredient in sea water from ${\text{Mg}}^{2+}$ salts before electrolysis.

(c)

Interpretation Introduction

To determine: The possibility of formation of elemental Magnesium by the electrolysis of ${\text{MgCl}}_2$ in an aqueous solution.

(d)

Interpretation Introduction

To determine: The products of electrolysis of water.
