Chapter 4, Problem 4.141AP

(a)

Interpretation Introduction

Interpretation: The questions corresponding to the reaction of sulfuric acid and calcium carbonate are to be answered.

Concept introduction: The reaction in which reduction and oxidation process occurs simultaneously is termed as redox reaction.

In oxidation there is loss of electrons occur which increases the oxidation state of an atom whereas in reduction process there is gaining of electrons occur which decreases the oxidation state of an atom.

To determine: If the given reactions are redox reactions or not and the number of electrons transferred.

(b)

Interpretation Introduction

To determine: A net ionic equation for the reaction between ${\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}$ with ${\text{CaCO}}_{\text{3}}$.

(c)

Interpretation Introduction

To determine: The difference between the net ionic equation and the given equation.
