Double Displacement Reaction: HBr and FeCl3

Chemistry is the study of matter, its properties, and its reactions with other substances. It is a complex field that requires a deep understanding of the laws of nature and how they apply to different chemical processes.

In this article, we will explore two topics related to chemistry- the reaction of HBr and

FeCl3 and the characteristics of ferric chloride (

FeCl3). We will learn about the products and type of reaction that occurs when HBr and

FeCl3 combine, as well as the oxidation state, anhydrous compound nature, color, and intermolecular structure of ferric chloride.

HBr and

FeCl3 Reaction

When hydrobromic acid (HBr) and ferric chloride (

FeCl3) are mixed, a double displacement reaction occurs. The products formed are ferric bromide (FeBr3) and hydrochloric acid (HCl).

The balanced chemical equation for this reaction is:

2HBr +

FeCl3 2HCl + FeBr3

The coefficient 2 in the equation signifies that two molecules of hydrobromic acid and one molecule of ferric chloride react to form two molecules of hydrochloric acid and one molecule of ferric bromide. It’s important to note that this reaction is irreversible.

Ferric bromide is the final product, and no further steps are required. Furthermore, this reaction is exothermic, meaning it releases heat.

The standard enthalpy of formation (Hf) of ferric bromide is -416.18 kJ/mol, indicating that it is a highly exothermic reaction. Unlike other reactions, the reaction of HBr and

FeCl3 isn’t a redox reaction.

There is no change in the oxidation state of any of the elements involved in the reaction. Additionally, there is no solid product formed in this reaction, so titration isn’t feasible.

The net ionic equation for this reaction doesn’t exist as the spectator ions and no reaction is taking place.

Ferric Bromide

Ferric bromide, also known as iron (III) bromide, is the compound formed as a result of the reaction between HBr and

FeCl3. It is a solid substance that has high ionic-dipole interaction, dipole-dipole interaction, and electrostatic attraction due to the presence of positive and negative ions.

Buffer solutions consisting of ferric bromide are often used in chemical procedures because of their high acidic strength. They are also effective in controlling reactions since ferric bromide reacts easily with strong acids.

Ferric bromide is a stable compound with a melting point of 311C. It is soluble in water, alcohol, and ether and readily forms bonds with other elements.

Unlike ferric chloride, ferric bromide is not a strong oxidizing agent; hence it is less corrosive when it comes in contact with human skin.

FeCl3

Ferric chloride is a compound consisting of iron and chlorine. Its chemical formula is

FeCl3.

Ferric chloride has an oxidation state of +3, making it useful for reactions that require the presence of a strong acid. It is also known as a Lewis acid, which means that it is capable of accepting a pair of electrons from a Lewis base to form a coordinate covalent bond.

Ferric chloride is typically found in anhydrous form, meaning it exists without any water molecules. However, it can also exist in hydrated form as hexahydrate, which contains six molecules of water.

It is because of the presence of water molecules that the color of ferric chloride changes with the viewing angle. The unique color of ferric chloride is due to its intermolecular structure, which reflects light in a different way than other substances.

This characteristic also makes it an excellent material for use in photography and printing. Ferric chloride is also used as a catalyst in chemical reactions, specifically as a coagulant in water treatment and as an etchant in the production of printed circuit boards.

Conclusion

Chemistry is a broad field that provides a deeper understanding of the world around us. In this article, we discussed the reaction of HBr and

FeCl3 and the characteristics of ferric chloride.

We learned that HBr and

FeCl3 react via a double displacement reaction producing FeBr3 and HCl. Furthermore, we explored the properties of ferric chloride, including its oxidation state, anhydrous compound nature, color, and intermolecular structure. We hope that this article has enhanced your knowledge of chemistry and its applications.

3) HBr

Hydrobromic acid (HBr) is a colorless gas that has a highly solubility in water, which enables it to dissolve easily in aqueous solutions. HBr is considered a strong acid because it completely dissociates in water to form H+ and Br- ions.

In its gaseous state, HBr forms a white fuming liquid due to the presence of hydrogen bromide gas, which causes the fuming effect.

One of the industrial uses of HBr is in the preparation of bromides.

Bromides are compounds formed by replacing the hydrogen within hydrogen bromide with other metals or non-metals to produce a salt. Aqueous solutions of bromides find application in the pharmaceutical industry for preparing sedatives and photography chemicals.

When HBr reacts with

FeCl3, a double displacement reaction occurs, which results in the formation of hydrochloric acid (HCl) and ferric bromide (FeBr3). This reaction is important in the synthesis of ferric bromide and other compounds that require the presence of a strong acid.

FeCl3 intermolecular structure and HBr industrial use in detail

Ferric chloride (

FeCl3) is a compound consisting of iron and chlorine, and it has a unique intermolecular structure that reflects light in a different way than other substances. This structure is responsible for the changing color of ferric chloride when viewed at different angles.

The intermolecular structure of ferric chloride reflects light in such a way that the color changes from brown to red to purple depending on the angle from which it is viewed. This unique property makes it an excellent material for use in photography and printing.

Furthermore, the intermolecular structure of ferric chloride is also responsible for its use as a catalyst in chemical reactions. As a coagulant, it is used in water treatment to remove impurities, bacteria, and other solids from water.

Ferric chloride is also used in the production of printed circuit boards as an etchant, which is used to remove copper from the board. Ferric chloride forms a complex with copper, which is then removed via washing.

On the other hand, HBr finds application in the preparation of bromides, which has a broad range of applications in the pharmaceutical industry. Aqueous solutions of bromides find application in the manufacturing of sedatives and photography chemicals.

HBr can also be used to improve the smoke suppressant property of chemicals. By adding HBr to certain chemicals, it reduces the amount of smoke produced during a fire.

In the synthesis of benzyl bromide, HBr is used to replace the hydrogen atom in benzene. The reaction is catalyzed by an iron halide such as FeBr3 to produce benzyl bromide.

Although the reaction can proceed without a catalyst, the use of FeBr3 together with HBr achieves higher yields.

In conclusion, ferric chloride and hydrobromic acid both play crucial roles in many industrial processes.

Ferric chloride’s unique intermolecular structure makes it ideal for printing and manufacturing printed circuit boards. It is also used as a coagulant in water treatment to remove impurities from water.

Hydrobromic acid, on the other hand, is a strong acid that finds application in the preparation of bromides, which is used extensively in the pharmaceutical industry. It is also used to improve the smoke suppressant property of certain chemicals.
