The Fascinating World of Chemistry: Exploring the Formation of Iron (III) Chloride and the Properties of Group VIII Elements

Chemistry is a fascinating field that involves the study of the composition, properties, and reactions of matter. In this article, we will explore a simple experiment that can be performed in the laboratory to demonstrate the formation of iron (III) chloride from iron filings. We will also delve into the properties of Group VIII elements and explain why all of them are gases at room temperature.

Experiment: Formation of Iron (III) Chloride

Materials

Iron filings
Hydrochloric acid (HCl)
Distilled water
A crucible or a heat-resistant container
A Bunsen burner or a hot plate

Procedure

Preparation of the Apparatus: Place the crucible or heat-resistant container on a heat-resistant surface. Add a small amount of iron filings to the crucible.
Addition of Hydrochloric Acid: Carefully add a few drops of hydrochloric acid to the iron filings. Observe the reaction and note the color change.
Heating the Mixture: Place the crucible over a Bunsen burner or a hot plate and heat the mixture until the iron filings are completely dissolved.
Cooling and Crystallization: Allow the mixture to cool slowly. As it cools, iron (III) chloride crystals will form.
Collection and Analysis: Collect the crystals and analyze their properties using various techniques such as spectroscopy or X-ray diffraction.

Discussion

The experiment demonstrates the formation of iron (III) chloride from iron filings through a chemical reaction with hydrochloric acid. The reaction can be represented by the following equation:

Fe (s) + 3HCl (aq) → FeCl3 (aq) + 3/2 H2 (g)

In this reaction, iron filings react with hydrochloric acid to form iron (III) chloride, which is a blue-colored solution. The reaction is an example of a single displacement reaction, where iron displaces hydrogen from hydrochloric acid to form iron (III) chloride.

Properties of Group VIII Elements

Group VIII elements are a series of elements that are located in the d-block of the periodic table. These elements are characterized by their ability to form ions with a +2 or +3 charge. The Group VIII elements are:

Scandium (Sc)
Yttrium (Y)
Lanthanum (La)
Actinium (Ac)
Radium (Ra)

Why are Group VIII Elements Gases at Room Temperature?

Group VIII elements are gases at room temperature because they have a very low boiling point. The boiling point of an element is the temperature at which it changes state from a liquid to a gas. Group VIII elements have a very low boiling point because they have a weak intermolecular force between their atoms. This means that they require very little energy to overcome the intermolecular forces and change state from a liquid to a gas.

Factors Contributing to the Low Boiling Point of Group VIII Elements

Several factors contribute to the low boiling point of Group VIII elements:

Weak Interatomic Forces: Group VIII elements have a weak interatomic force between their atoms. This means that they require very little energy to overcome the interatomic forces and change state from a liquid to a gas.
Small Atomic Size: Group VIII elements have a small atomic size, which means that they have a small number of electrons in their outermost energy level. This results in a weak intermolecular force between their atoms.
High Ionization Energy: Group VIII elements have a high ionization energy, which means that they require a lot of energy to remove an electron from their outermost energy level. This results in a weak intermolecular force between their atoms.

Conclusion

In conclusion, the formation of iron (III) chloride from iron filings is a simple experiment that can be performed in the laboratory to demonstrate the properties of iron and its compounds. The experiment also highlights the importance of understanding the properties of elements and their compounds in chemistry. Additionally, the properties of Group VIII elements and their ability to form ions with a +2 or +3 charge make them an interesting topic of study in chemistry.
