Chapter 9, Problem 102A

Interpretation Introduction

Interpretation: The complete ionic equation and net ionic equations for the given word chemical reaction need to be determined.

Concept Introduction: Chemical equation is the symbolic description of a chemical reaction that products and reactants are indicating in terms of their chemical formula.

Answer to Problem 102A

The complete ionic equation is as follows.

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

The net ionic equation for a given reaction is as follows:

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

Explanation of Solution

For the given word reaction, the chemical equation is as follows:

  ${\text{H}}_{\text{2}}{\text{SO}}_{\text{3}}\left(aq\right)+\text{NaOH}\left(aq\right)\to {\text{Na}}_{\text{2}}{\text{SO}}_{\text{3}}\left(aq\right)+{\text{H}}_{\text{2}}\text{O}\left(l\right)$

Now balance the above equation is as follows:

  ${\text{H}}_{\text{2}}{\text{SO}}_{\text{3}}\left(aq\right)+2\text{NaOH}\left(aq\right)\to {\text{Na}}_{\text{2}}{\text{SO}}_{\text{3}}\left(aq\right)+2{\text{H}}_{\text{2}}\text{O}\left(l\right)$

The ionized form of given chemical reactants and products is as follows:

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

The net ionic equation eliminates all ions which are shared by both sides. Thus, the net ionic equation is as follows:

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

Conclusion

The net ionic equation eliminates all ions which are shared by both sides. The net ionic equation for the given reaction is as follows:

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

The complete ionic equation is as follows:

  ${\text{H}}_{\text{2}}{\text{SO}}_{\text{3}}\left(aq\right)+2\text{NaOH}\left(aq\right)\to {\text{Na}}_{\text{2}}{\text{SO}}_{\text{3}}\left(aq\right)+2{\text{H}}_{\text{2}}\text{O}\left(l\right)$

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