Ferric Hydroxide and Sulfurous Acid: Benefits and Safety Precautions

Chemistry is the study of matter and the changes it undergoes. In this article, we will focus on the reaction between H2SO3 and Fe(OH)3, as well as the properties of the chemical compounds involved.

Reaction between H2SO3 and Fe(OH)3

When H2SO3 and Fe(OH)3 react, ferric sulfite (Fe2(SO3)3) and water (H2O) are obtained. This reaction is exothermic, meaning that energy is released during the reaction.

The type of reaction that occurs is a neutralization reaction. This is because H2SO3 is a weak acid, while Fe(OH)3 is a weak base.

When they react, they neutralize each other, forming a salt and water. The reaction can be balanced using mole numbers and an equation.

The balanced equation is: 2H2SO3 + 3Fe(OH)3 Fe2(SO3)3 + 6H2O. This equation shows that two molecules of H2SO3 and three molecules of Fe(OH)3 react to form one molecule of Fe2(SO3)3 and six molecules of H2O.

The conjugate pairs of the reaction are H2SO3/HSO3- and H2O/OH-. H2SO3 is an acid because it donates a proton (H+) to HSO3-.

H2O is a base because it accepts a proton (H+) from a reactant to form OH-.

Intermolecular forces

There are four types of intermolecular forces: interionic Columbic force, dipole-dipole interaction, London dispersion forces, and hydrogen bonding. In this reaction, the intermolecular forces involved are electrostatic force, dipole-dipole interaction, London dispersion forces, and hydrogen bonding.

Titration and net ionic equation

Titration is a technique used to determine the concentration of a solution by reacting it with another solution of a known concentration. In this reaction, H2SO3 is the weak acid, while Fe(OH)3 is the weak base.

The net ionic equation for the reaction is: 2H+ + 3OH- 6H2O. This equation shows that two protons (H+) from H2SO3 react with three hydroxide ions (OH-) from Fe(OH)3 to form six molecules of water (H2O).

Buffer solution and precipitation/reversibility of the reaction

A buffer solution resists changes in pH when small amounts of an acid or base are added to it. In this reaction, H2SO3 and Fe(OH)3 can act as a buffer solution because they are weak acid and weak base, respectively.

The reaction between H2SO3 and Fe(OH)3 is a complete reaction, meaning that all the reactants are converted into products. It is also irreversible because the products cannot react to form the reactants again.

This is because one of the products, water, is a stable compound.

Properties of chemical compounds involved

The formation enthalpy of H2SO3 is -483 kJ/mol, while that of Fe(OH)3 is -943 kJ/mol. The formation enthalpy of H2O is -285.8 kJ/mol.

The negative enthalpy indicates that these reactions release energy. The intermolecular forces acting on H2SO3 and Ferric hydroxide are electrostatic force, dipole-dipole interaction, London dispersion forces, and hydrogen bonding.

The electrostatic force exists between the ions in the compounds, while the dipole-dipole interaction occurs between molecules that have a permanent dipole moment. The London dispersion forces occur between all molecules, while the hydrogen bonding occurs between molecules that contain hydrogen atoms and either oxygen, nitrogen, or fluorine atoms.

In conclusion, the reaction between H2SO3 and Fe(OH)3 results in the formation of ferric sulfite and water in an exothermic neutralization reaction. The conjugate pairs involved in the reaction are H2SO3/HSO3- and H2O/OH-.

The intermolecular forces involved are electrostatic force, dipole-dipole interaction, London dispersion forces, and hydrogen bonding. The reaction is a complete reaction and is irreversible.

The formation enthalpies of H2SO3, Fe(OH)3, and H2O are negative, indicating that energy is released during their formation. Ferric hydroxide and sulfurous acid are both chemical compounds that have a variety of uses in different industries.

In this article expansion, we will dive deeper into their applications and benefits.

Ferric hydroxide as an iron supplement

Ferric hydroxide is a compound that is essential for proper body functioning. It is rich in iron, and it is often used as a supplement for individuals with iron-deficiency anemia.

Iron-deficiency anemia is a condition that results from a deficiency of iron in the body, leading to fatigue, weakness, and shortness of breath. Ferric hydroxide is an excellent iron supplement because it is easily digestible and does not cause gastrointestinal distress.

Moreover, it is effective in boosting hemoglobin levels in the blood, the protein responsible for carrying oxygen throughout the body. Iron deficiency anemia is a prevalent condition globally, and ferric hydroxide supplements have helped alleviate this problem.

Sulfurous acid in various industrial uses

Sulfurous acid is a compound formed when water and sulfur dioxide (SO2) combine. It has several industrial applications in the manufacture of fertilizers, dyes, detergents, and inorganic salts.

Fertilizers: Sulfurous acid is used in the production of fertilizers since the sulfur in the compound is essential for plant growth. Plants require sulfur to produce vital amino acids, enzymes, and proteins.

Additionally, sulfur aids in the stimulation of plant growth and the improvement of crop yield. Dyes: Sulfurous acid is used in the dyeing industry to make sulfur dyes.

Sulfur dyes are inexpensive and are commonly used to color fabrics such as cotton, wool, and silk. These dyes are highly resistant to fading and have good color-fastness.

Detergents: Sulfurous acid is used in the production of detergents, where it acts as a reducing agent. It helps to reduce the levels of chlorine in the detergent, allowing for a more eco-friendly product.

It also eliminates malodors from the detergent, thus making them more attractive to consumers. Inorganic Salts: Sulfurous acid is used in the synthesis of several inorganic salts such as sodium sulfite, sodium bisulfite, and sodium metabisulfite.

Sodium sulfite and sodium bisulfite are used as antioxidants, food preservatives, and in the treatment of skin sensitivities. Sodium metabisulfite, on the other hand, is used as a preservative in the food and beverage industry.

Safety considerations

While Ferric hydroxide and sulfurous acid have numerous benefits, safety precautions should be taken when handling these compounds. Ferric hydroxide supplements should only be taken under the guidance of a medical professional since excessive intake can lead to iron overload, which can be harmful to the body.

Sulfurous acid is a highly reactive compound that requires proper handling to avoid accidents. It is also important to note that sulfurous acid can cause respiratory irritations, and long-term exposure to the compound can lead to chronic respiratory conditions.

Conclusion

Ferric hydroxide and sulfurous acid are two vital chemical compounds with various industrial applications. Ferric hydroxide is an excellent iron supplement that helps alleviate iron-deficiency anemia, while sulfurous acid is used in the manufacture of several essential industrial products such as fertilizers, dyes, detergents, and inorganic salts.

However, it is important to handle these compounds with caution and follow the recommended guidelines when using them to prevent adverse effects on health and safety. Ferric hydroxide and sulfurous acid are two important chemical compounds with various uses.

Ferric hydroxide is an effective iron supplement that helps alleviate iron-deficiency anemia, while sulfurous acid is utilized in the manufacture of fertilizers, dyes, detergents, and inorganic salts. Proper safety measures should be taken when handling these compounds, as excessive use of Ferric hydroxide can cause iron overload while excessive exposure to sulfurous acid can lead to chronic respiratory issues.

Although they are essential, it is essential to handle these compounds with care to prevent harm to oneself and the surroundings.
