Chapter 23, Problem 44QP

Interpretation Introduction

Interpretation:

The process of formation of calcium carbonate, starting from calcium oxide, is to be described and balanced chemical reaction to be written.

Concept introduction:

Calcium oxide is a solid thatis a white crystalline with a melting point of ${\text{2572}}^{\text{o}}\text{C}$. This compound is manufactured by heating limestone, coral, sea shells, or chalk, which are mainlycomposed of ${\text{CaCO}}_{\text{3}}$, to drive off carbon dioxide.

The reaction is reversible; calcium oxide will undergo a chemical reaction with carbon dioxide in order toformcalcium carbonate.

Calcium hydroxide $\text{Ca}{\left(\text{OH}\right)}_{\text{2}}$ is commonly known as slaked lime or hydrated lime.

Calcium oxide $\text{CaO}$ or lime is also known as quick lime.
