Chapter 21, Problem 21.7QP

Interpretation Introduction

Interpretation:

The equations for the preparation of magnesium metal from seawater, limestone, and hydrochloric acid has to be written.

Concept introduction:

Dow process:

• In Dow process, using seawater, limestone, and hydrochloric acid we can synthesis the pure magnesium metal.
• Seawater contains ${\text{CaCO}}_{\text{3}}$ and which is a base and first step of the preparation of magnesium in Dow process.
• Then gradually doing the step by step process of Dows process we can get the pure magnesium metals at final stage by electrolysis.
