Chapter 19, Problem 117SAE

Interpretation Introduction

Interpretation:

Consequences occur if cobalt metal is added to an aqueous solution in which $\left[{\text{Ni}}^{2+}\right]=1.0\text{ M}$ should be determined.

Concept introduction:

If a redox reaction is spontaneous, then its standard cell potential should be positive. Standard cell potential can be determined by

${\text{E}}_{cell}^0={\text{E}}_{catode}^0-{\text{E}}_{anode}^0$

Cathode is the electrode which reduction takes place and anode is the electrode which oxidation takes place.
