Chapter 4, Problem 4.134P

Interpretation Introduction

Interpretation:

The mass percent of dolomite $\left[\text{CaMg}{\left({\text{CO}}_3\right)}_2\right]$ in the $13.86\text{g}$ soil is to be calculated.

Concept introduction:

Strong acids and strong bases are the substance that dissociates completely into its ions when dissolved in the solution. They dissociates completely in water to release ${\text{H}}^{+}$ ions and ${\text{OH}}^{-}$ ions.

Weak acids and weak bases are the substance that do not dissociates completely into its ions when dissolved in the solution. They dissociate partially in water to release ${\text{H}}^{+}$ ions and ${\text{OH}}^{-}$ ions.

The driving force of the acid-base reaction is the formation of gaseous product or precipitate in the reaction. The formation of water molecule also acts as a factor to drive the reaction to completion.
