Chapter 11.3, Problem 25SP

Interpretation Introduction

Interpretation: To determine the net ionic equation of the given reaction.

Concept Introduction: In general, an ionic reaction occurs when anions, as well as cations, combine to generate a compound in a liquid or solid media. Water-insoluble salts are created whenever the ions of salts that are soluble in water communicate with one another.

Answer to Problem 25SP

The net ionic equation will be ${\text{H}}^{\text{+}}\left(\text{aq}\right){\text{+OH}}^{\text{-}}\text{(aq)}\to {\text{H}}_{\text{2}}\text{O(l)}$

Explanation of Solution

The given ionic equation is:

  ${\text{Ca}}^{2+}{\text{(aq)+PO}}_4^{3-}{\text{(aq)+H}}^{\text{+}}\left(\text{aq}\right){\text{+OH}}^{\text{-}}\text{(aq)}\to {\text{H}}_{\text{2}}\text{O(l)}\to {\text{Ca}}^{2+}{\text{(aq)+PO}}_4^{3-}\text{(aq)}+{\text{H}}_{\text{2}}\text{O(l)}$

Calcium ion and phosphate ion will be canceled out hence, the net ionic equation will be

  ${\text{H}}^{\text{+}}\left(\text{aq}\right){\text{+OH}}^{\text{-}}\text{(aq)}\to {\text{H}}_{\text{2}}\text{O(l)}$
