Chapter 4, Problem 4.61P

(a)

Interpretation Introduction

Interpretation:

The factor responsible for the completion of the following acid-base reaction is to be determined.

  ${\text{MgSO}}_3\left(s\right)+2\text{HCl}\left(aq\right)\to {\text{MgCl}}_2\left(aq\right)+{\text{SO}}_2\left(g\right)+{\text{H}}_2\text{O}\left(l\right)$

Concept Introduction:

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

Weak acids and weak bases are the substance that does not dissociate 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 a gaseous product or precipitate in the reaction. The formation of a water molecule also acts as a factor to drive the reaction to completion.

(b)

Interpretation Introduction

Interpretation:

The factor responsible for the completion of the following acid-base reaction is to be determined.

  $\text{3Ba}{\left(\text{OH}\right)}_2\left(s\right)+2{\text{H}}_3{\text{PO}}_4\left(aq\right)\to {\text{Ba}}_3{\left({\text{PO}}_4\right)}_2\left(aq\right)+6{\text{H}}_2\text{O}\left(l\right)$
