Chapter 19, Problem 19.107QP

(a)

Interpretation Introduction

Interpretation:

Oxidation of nickel by iron(III) ion under standard reaction conditions is a spontaneous one or nonspontaneous one has to be given.

Concept introduction:

Strengths of and Reducing Agents:

In electrochemistry Standard electrode potential are used to determine the strengths of oxidizing and reducing agents.

The more positive value containing species act as a stronger oxidizing agent and more negative value containing species act as a stronger reducing agent.

(b)

Interpretation Introduction

Interpretation:

Tin(II) ion will be oxidized to Tin(IV) under standard conditions by iron(III) or not has to be given.

Concept introduction:

Strengths of and Reducing Agents:

In electrochemistry Standard electrode potential are used to determine the strengths of oxidizing and reducing agents.

The more positive value containing species is acts as a stronger oxidizing agent and more negative value containing species is acts as a stronger reducing agent.
