Let’s go through five chemical reactions with iron.

1) Reaction of iron and sulfuric acid. This reaction is active, the iron is completely dissolved in the acid and an iron sulfate salt is formed and hydrogen gas is released.

Fe + H2SO4 = FeSO4 + H2

We compose the equation of electronic balance:

Fe 0 – 2 e = Fe 2+ oxidation process, therefore a reducing agent,

2 H + + 1 e = H2 0 is a reduction process, hence an oxidizing agent.

2) Reaction of iron and acidic salt of copper sulfate. There is also the formation of a salt of ferrous sulfate, as well as pure copper.

Fe + CuSO4 = FeSO4 + Cu

We compose the equation of electronic balance:

Fe 0 – 2 e = Fe 2+ oxidation process, therefore a reducing agent,

Cu 2+ + 2 e = Cu 0 is a reduction process, hence an oxidizing agent.

3) Chemical reaction of iron and calcium chloride salt in solution. Such a chemical reaction is not possible, since calcium is located to the right in the row of electrical voltage than iron.

Fe + CaCl2 = no reaction.

4) A chemical reaction takes place between substances such as iron and silver nitrate salt. We get iron nitrate salt and pure silver.

Fe + 2 AgNO3 = Fe (NO3) 2 + 2 Ag

Fe 0 – 2 e = Fe 2+ oxidation process, therefore a reducing agent,

Ag + + 1 e = Ag 0 is a reduction process, hence an oxidizing agent.

5) The chemical reaction between iron and sodium chloride salt does not take place. Since sodium in the row of electrical voltage is located to the right of iron.

Fe + NaCl = no reaction.
