Hydrochloric acid can be found in both liquid and gaseous (hydrogen chloride) forms. Iron(III) Oxide(Fe₂O₃) is naturally found as Haematite ore in rocks and can be prepared from even normal oxidation of Iron. These crystals have various polymorphs and are used in the production of Iron and such alloys.

In this article, we will observe the reaction properties and products of the acid and the metal oxide.

What is the product of HCl and Fe₂O₃?

HCl and Fe₂O₃ react lớn khuông Ferric Chloride and water respectively. The reaction equation is:

• Fe₂O₃ + 6HCl =  2FeCl₃ +  3H₂O

What type of reaction is HCl + Fe₂O₃?

The reaction of HCl with Fe₂O₃ is a neutralisation reaction as the amphoteric Iron oxide reacts with the acid lớn give salt and water.

How lớn balance HCl and Fe₂O₃?

Following are the steps lớn equate the above reaction scheme:

• Step 1: Put the general chemical equation:
• Fe₂O₃ + HCl =  FeCl₃ +  H₂O
• Step 2: As both sides should be equal in atoms, keeping in mind the stoichiometry, multiply FeCl₃ with 2 lớn equate the Iron atoms.
• Fe₂O₃ + HCl =  2FeCl₃ +  H₂O
• Step 3: Equate the Oxygen atoms per unit of the compound.
• Fe₂O₃ + HCl =  2FeCl₃ +  3H₂O
• Step 4: Since product side has 6 chlorine atoms per unit, the reaction should be equaled with the same number.
• Fe₂O₃ + 6HCl =  2FeCl₃ + 3H₂O

HCl + Fe₂O₃ Titration

The measurement of Fe₂O₃ is performed by a method called gravimetric analysis, primarily involving hydrochloric acid solution. Following is the overall procedure required with specific apparatus:

Apparatus Used

• Conical flask
• Beakers
• Filter Paper
• Bunsen Burner

Procedure

• The oxide is solvated in the hydrochloric acid medium in a conical flask.
• The conical flask is heated with ammonia and a few drops of dilute nitric acid are added. The solution is stirred for some time.
• The medium is washed lớn keep away impurities and it is repeated.
• The solution is filtered and washed again.
• A sticky reddish precipitate is obtained which is soluble in dilute acids
• It is heated and dried lớn measure purity. Any pieces of filter paper are added and the process is repeated.
• The amount of Ferric oxide obtained is measured,
• Weight of Iron is found by mathematical calculations.

HCl + Fe₂O₃ Net Ionic Equation

HCl + Fe₂O₃ net ionic equation stands as the formation of Iron(III) ions and Chloride ions along with the proton and hydroxyl ions from water.

• 2Fe²⁺(aq) +  3O^2-(aq) + H⁺(aq) + Cl^–(aq) =  2Fe³⁺(aq)+ 3Cl^–(aq) +  H⁺(aq) +  OH^–(aq)

HCl + Fe₂O₃ Conjugate Pairs

Conjugate acid-base pairs refer lớn those pairs of compounds where the chemical difference between them is just one proton. For instance,

• Conjugate base of HCl= Cl^–
• Conjugate base of H₂O = OH^–

HCl and Fe₂O₃ Intermolecular Forces

HCl shows ionic interactions in an aqueous medium. On comparing electronegativity values, Fe₂O₃ is found lớn be polar covalent in nature due lớn small size of Fe³⁺ ion. FeCl₃ produces electrostatic interactions, with London dispersion forces due lớn polarization of electron cloud in chlorine.
