15 Facts on HCl + CH3COOH: With Several Elements Reaction

HCl+ CH₃COOH is a special type of reaction in chemistry. Let us canvas different properties and reactions of this reaction.

Both are acids in the HCl+ CH₃COOH reaction, but HCl is a strong acid, and CH₃COOH is a weak acid. This reaction comes under the acid-base reaction.

Let us investigate some of the properties of this reaction, like its product, type of reaction, enthalpy, and intermolecular forces.

What is the product of HCl and CH₃COOH?

HCl is a strong acid that suppresses the dissociation of acetic acid, and the weak acetic acid remains in its molecular form. So strong acid HCl donates H+ ion to the molecular acetic acid to form acetonium ion.

HCl + CH₃COOH = CH₃COOH₂⁺ + Cl^–

What type of reaction is HCl + CH₃COOH

HCl + CH₃COOH is an acid-base reaction.HCl is a strong acid, and CH₃COOH is also an acid, but it is a weak acid.

How to balance HCl + CH₃COOH

There is no need to balance the reaction of HCl + CH₃COOH. Because in this reaction of HCl and CH₃COOH, acetic acid does not react with hydrochloric acid, HCl being a strong acid, donates its proton to acetic acid-forming CH₃COOH₂⁺.

HCl + CH₃COOH titration

Apparatus

 Burette, pipette, burette stand, measuring jar, conical flask, wash bottle..

Indicator

 Phenolphthalein indicator is used in the acid-base titration. End point for the acid-base titration is pink to colorless

Procedure

Acid HCl is taken in a beaker, and the base should be filled in the burette and start titrating against the base near the equivalence point; we have to add an acid-base indicator phenolphthalein which is having P^H 8.2-10. The point at which the color disappears is the endpoint chemically called an equivalent point.

HCl + CH₃COOH net ionic equation

CH₃COOH is a weak acid, so it cannot be shown to be completely dissociated at a time. So, it is partially dissociated in an aqueous solution, so this dissociation of acetate ions is not considered a spectator ions. So we cannot clearly give the net ionic equation for this.

CH₃COO^–_(aq) + H⁺_(aq) + Cl^–_(aq) –> CH₃COOH_(aq) + Cl^–_(aq)

Net ionic equation

CH₃COO^–_(aq)+ H⁺_(aq) –> CH₃COOH_(aq)

Conjugate acid-base pair

• Conjugate acid is the base capable of accepting proton(H⁺) to an acid.
• The conjugate base is the acid capable of donating a proton(H⁺) to a base.

• In this reaction, HCl and Cl ^– are conjugate acid-base pairs and CH₃COOH and CH₃COOH₂⁺ are another conjugate acid-base pair.

HCl and CH₃COOH intermolecular forces

• In HCl, intermolecular forces between hydrogen and chloride ions are dipole-dipole interactions and London dispersion intermolecular forces.
• But dipole-dipole interactions are very strong as compared to London dispersion forces in hydrochloric acid.
• In acetic acid hydrogen bonding, dipole-dipole interactions and dispersion forces are present between the molecule.

HCl + CH₃COOH reaction enthalpy

The enthalpy for the neutralization reaction of HCl + CH₃COOH is −49.86 kJ/Mol. It can be calculated by eliminating the sum of the enthalpies of the products ( CH₃COOH₂⁺ + Cl^–)from the sum of the enthalpies of reactants(CH₃COOH + HCl).

Is HCl + CH₃COOH a buffer solution

HCl + CH₃COOH is not a buffer solution because of their P^H values. Since the acetic acid p^H value is 2.4, while the hydrochloric acid pH value is 1.1.

Is HCl + CH₃COOH a complete reaction

HCl + CH₃COOH is not a complete reaction because the acetic acid is not completely dissociating into the aqueous solution, so we can’t be aware of the dissociation reaction; this is usually due to the common ion effect.

Is HCl + CH₃COOH an exothermic

 HCL + CH₃COOH is an exothermic reaction because CH₃COOH being a weak acid, doesn’t react with HCl.HCl strong acid, so no external energy is required to break the bond.

Is HCl + CH₃COOH a redox reaction

HCl + CH₃COOH is not a redox reaction since only the proton has been transferred from the acid to the base. There is no change in the oxidation state of reactants and products.

Is HCl + CH₃COOH a precipitation reaction

Acetic acid does not undergo any reaction with hydrochloric acid; only proton transfer takes place, so there is no scientific evidence for precipitation formation.

Is HCl + CH₃COOH reversible or irreversible reaction

In the HCl+ CH₃COOH reaction, acetic acid, a weak acid, undergoes a reversible reaction since it partially dissociates into the aqueous solution. But due to the strong acid HCl does not permit the acetic acid to dissociate into ions.

CH₃COOH = CH₃COO^– +H⁺

Is HCl + CH₃COOH displacement reaction

HCl + CH₃COOH reaction can be considered a single displacement reaction as a proton is displaced from strong acid HCl to Weak acid CH₃COOH.

How to balance CH₃COOH + HCl + NaOH = CH₃COOCl + Na + H₂O

To balance any equation, we must be sure that the number of atoms of every element on both the reactants side and the products side must be equal. Then we have to multiply the atoms until both sides have the number of atoms equal. Therefore, the balanced chemical equation is:

CH₃COOH + HCl +2NaOH → CH₃COOCl + 2Na + 2H₂O

Conclusion

This article summarizes the reaction of HCl+CH₃COOH is a type of acid-base ionization reaction.
