Chapter 5, Problem 122QP

Interpretation Introduction

Interpretation:

Three metals than can cause cobalt to be plated out from an aqueous solution of cobalt (II) chloride are to be identified.

Concept Introduction:

The reactivity of metals are studied on the basis of the reactivity series. The metals that are more reactive than hydrogen are placed at higher positions and metals that are less reactive than hydrogen are placed below it in the reactivity series. A more reactive metal displaces a less reactive metal from the solution.
