HCl + FeS₂ does not exhibit conjugation as it is observed in acid-base pairs where there is an exchange of H⁺ ions and the formation of conjugate acids and bases. But HCl + FeS₂ undergoes disproportionation which makes conjugation impossible.

HCl and FeS₂ intermolecular forces

HCl + FeS₂ reaction can have the following intermolecular forces,

• HCl is a strong mineral acid that exhibits the London dispersion forces and the dipole-dipole interaction due lớn major electronegativity differences between H⁺ and Cl^– ions.
• FeS₂ is an ionic crystal structure due lớn which it shows ionic properties and strong electrovalent properties.

Is HCl + FeS₂ a complete reaction?

HCl + FeS₂ is a complete reaction because the equilibrium of the reaction is achieved and there is no reversal. Also, the concentration of reactants and products is not changing continuously. This also implies that the concentration of reactants has become zero after completion.

Is HCl + FeS₂ an exothermic or endothermic reaction?

HCl + FeS₂ is an exothermic reaction as the reaction between an acid and a metal compound produces heat in the product. In HCl + FeS₂ reaction H₂S and S are produced which generate heat and energy.

Is HCl + FeS2 a redox reaction?

Is HCl + FeS2 a precipitation reaction?

HCl + FeS₂ is not a precipitation reaction as there are no insoluble products formed which settle at the bottom of the reaction mixture and then recrystallize. The product FeCl₂ formed is aqueous and is separated by chemical washings.

Is HCl + FeS₂ a reversible or irreversible reaction?

HCl + FeS₂ is an irreversible reaction as the equilibrium is in a forward reaction and the phases of the products cannot be reversed. Here FeCl₂ is in an aqueous phase and H₂S formed solidifies thereby restricting the backward reaction.

Is HCl + FeS₂ displacement reaction?

HCl + FeS₂ is not a displacement reaction as there are no exchanges between the cations and anions of the reactants which sườn the products. Instead, it is a disproportionation reaction.

Conclusion

Concluding the article then HCl + FeS₂ is a redox reaction with an exception where only FeS₂ is both an oxidation and reducing agent. It is lượt thích any other inorganic reaction between an acid and a metal compound which could lead lớn corrosion of the metal involved and produce heat in the process.
