<span>Electronegative atoms or atoms where electrons spend more of their time orbiting the atom's nucleus giving the atom a negative charge. When electronegative atoms such as oxygen bond to hydrogen they pull the hydrogen's electron to themselves becoming even more electronegative. This causes the hydrogen side to become positive. The molecule formed is a polar molecule. Molecules with positive ends and negative ends are called polar.</span>

To demonstrate the formation of iron (iii) chloride from iron fillings
Pavel [41]

Iron (iii) chloride is obtained by vapor condensation from the reaction between chlorine gas and iron fillings.

<h3>How can iron (iii) chloride be formed from iron fillings?</h3>

Iron (ii) chloride can be formed from iron fillings in the laboratory as follows:

  • Iron fillings + Cl₂ → FeCl₃

Chlorine gas is introduced into a reaction vessel containing iron fillings and the iron (iii) chloride vapor formed is obtained by condensation.

In conclusion, iron (iii) chloride is formed by the the direct combination of iron fillings and chlorine gas.
