Hydrochloric acid, muriatic acid, is an aqueous hydrochloride solution. In contrast, sodium bromide is a neutral salt. Let us learn about the reaction of HCl + NaBr in detail.
HCl react with NaBr to give a neutraslisation reaction. Hydrochloric acid is a strong acid. It is colorless and has a distinctively pungent smell. In contrast, sodium bromide is a salt of strong acid, i.e., HBr and a strong base, i.e., NaOH. It is typically used in the oil and gas drilling industry.
In this article, we shall discuss the kind, product, and balancing of the HCl + NaBr reaction.
What is the product of HCl and NaBr?
NaCl and HBr is formed on reaction of HCl and NaBr.
HCl + NaBr → NaCl + HBr
What type of Reaction is HCl + NaBr
HCl + NaBr is a double displacement reaction as the ions of the two compounds exchange their site to form two different compounds.
How to Balance HCl + NaBr
The equation is balanced by the hit and trial method by using the following steps.
HCl + NaBr → NaCl + HBr
- First, we will write the unbalanced chemical equation.
- Then, we will compare the atoms of the reactant side with the product side by the hit-and-trial method.
| Reactant Side | Product Side |
|---|---|
| 1 Hydrogen atom from Hydrochloric Acid | 1 Hydrogen atom from Hydrobromic Acid |
| 1 Chlorine atom from Hydrochloric Acid | 1 Chlorine atom from Sodium Chloride |
| 1 Sodium atom from Sodium Bromide | 1 Sodium atom from Sodium Chloride |
| 1 Bromine atom from Sodium Bromide | 1 Bromine atom from Hydrobromic Acid |
We can see that the atoms of the reactant side are equivalent to the atoms of the product side. Thus, the equation is already balanced.
HCl + NaBr Titration
HCl + NaBr does not undergo titration as there is no equivalence point.
HCl + NaBr Net Ionic Equation
The net ionic equation of HCl + NaBr is
H+ + Br– → HBr.
To derive the net ionic equation, the following steps are used.
- To write the net ionic equation of HCl + NaBr, first, we shall write the complete equation along with their state. Here, HCl, NaBr, NaCl and HBr exist in aqueous state.
- HCl (aq) + NaBr (aq) → NaCl (aq) + HBr (aq)
- Thus, can write the complete net ionic equation for the above balanced equation as follows:
- H+ + Cl– + Na+ + Br– → Na+ + Cl– + HBr
- Cl– and Na+ is present in reactant as well as product, thus will get cancelled out.
- Hence, the net equation will be:
- H+ + Br– → HBr
HCl + NaBr Conjugate Pairs
- The hydrochloric acid’s conjugate base is Cl–.
- There is no conjugate pair of NaBr as it contains no proton.
HCl and NaBr Intermolecular Forces
- HCl contains dipole-dipole intermolecular forces of attraction.
- NaBr contains an electrostatic force of attraction.
Is HCl + NaBr a Buffer Solution
HCl + NaBr is not a buffer solution as it contains a strong acid and a neutral salt.
Is HCl + NaBr a Complete Reaction
HCl + NaBr is not a complete reaction as it never attains equilibrium, i.e., the concentration of reactants and products keeps changing.
Is HCl + NaBr an Endothermic Reaction
HCl + NaBr is an endothermic reaction as the value of delta G is positive.
Is HCl + NaBr a Redox Reaction
HCl + NaBr is not a redox reaction, as the oxidation state of the elements remains the same.
Is HCl + NaBr a Precipitation Reaction
HCl + NaBr is not a precipitation reaction, as no insoluble sediment is deposited during the reaction.
HCl + NaBr → No precipitate
Is HCl + NaBr Reversible Reaction
HCl + NaBr is a reversible reaction,i.e., we can extract reactants from the product.
Is HCl + NaBr Displacement Reaction
HCl + NaBr is a displacement reaction as the chloride ion displaces the bromide ion from sodium bromide to form sodium chloride. And the hydrogen ion replaces the sodium ion from sodium bromide to form hydrobromic acid.
HCl + NaBr → NaCl + HBr
Conclusion
Hydrochloric acid reacts with sodium bromide to give a salt metathesis reaction or double displacement reaction forming hydrobromic acid and sodium chloride. It is an endothermic, reversible reaction. The oxidation state remains constant during the reaction.
