Chapter 5, Problem 112SAE

Interpretation Introduction

Interpretation:

The missing coefficient in the given reaction needs to be determined.

${\text{x Fe}}^{\text{2+}}\left(\text{aq}\right){\text{ + O}}_{\text{2}}\left(\text{g}\right){\text{ + 4 H}}^{\text{+}}\left(\text{aq}\right)\to {\text{ x Fe}}^{\text{3+}}\left(\text{aq}\right){\text{ + 2 H}}_{\text{2}}\text{O }\left(\text{l}\right)$

Concept introduction:

The net ionic equation for a reaction shows the species reacting.

These ions react to produce desired product in the reaction which may also include the spectator ion or ions which are repeating in the reaction. Thus, these ions get cancelled out in the net ionic equation.
