An iron storage tank is placed in the ocean with no cathodic protection. a. What is the electrolyte in this reaction? b. As the

MariettaO [177]

Answer:

Iron is being oxidized at the anode and water is acting as the electrolyte.

Explanation:

When iron is exposed to oxygen and water , the rusting of iron takes place.

<u>The reaction taking place at anode : Oxidation of iron.</u>

${anode:}\;\text{Fe}(s)\;{\longrightarrow}\;\text{Fe}^{2+}(aq)\;+\;2\text{e}^{-}$

The reaction taking place at cathode : Reduction of oxygen in the air.

${cathode:}\;\text{O}_2(g)\;+\;4\text{H}^{+}(aq)\;+\;4\text{e}^{-}\;{\longrightarrow}\;2\text{H}_2\text{O}(l)$

The overall reaction:

${overall:}\;2\text{Fe}(s)\;+\;\text{O}_2(g)\;+\;4\text{H}^{+}(aq)\;{\longrightarrow}\;2\text{Fe}^{2+}(aq)\;+\;2\text{H}_2\text{O}(l)$

The rust that is hydrated iron(III) oxide can form iron(II) ions which can react further with oxygen.

$4\text{Fe}^{2+}(aq)\;+\;\text{O}_2(g)\;+\;(4\;+\;2x)\;\text{H}_2\text{O}(l)\;{\longrightarrow}\;2\text{Fe}_2\text{O}_3{\cdot}x\text{H}_2\text{O}(s)\;+\;8\text{H}^{+}(aq)$

Thus, from the above reactions ,

Iron is being oxidized at the anode and water is acting as the electrolyte.
