Let us learn about the chemical reaction with a unique mechanism, fascinating chemistry, and intriguing features. The interaction between sulfuric acid and aluminum bromide is described below.
As its chemical formula indicates, sulphuric acid (H2SO4), the most potent acid, Aluminum bromide AlBr3, is an ionic chemical. The IUPAC term for this is “tribromoalumane,” although you might know it better as “tribromide of aluminum.”
We can now talk about the reaction’s mechanism, including enthalpy, reaction type, intermolecular force, conjugate pairs, and learn more about them in the following article.
What is the product of H2SO4 and AlBr3

H2SO4 and AlBr3 intermolecular forces
- H2SO4 and AlBr3 held by The intermolecular forces that exist in sulfuric acid are by Van der Waals forces,
- Whereas AlBr3 is primarily covalent bonded up until the point that it dissolves in water,
H2SO4 and AlBr3 reaction enthalpy
H2SO4 and AlBr3 reaction is exothermic, resulting in a decrease in enthalpy.
Is H2SO4 and AlBr3 a buffer solution
H2SO4 and AlBr3 mixture cannot serve as a buffer solution as strong acid (H2SO4), and ionic slat (AlBr3) is salt, which does not yield a buffer solution.
Is H2SO4 and AlBr3 a complete reaction
H2SO4 and AlBr3 is complete reaction. Here, the reactant’s components combine to create HBr, marking the process’s end.
Is H2SO4 and AlBr3 an exothermic or endothermic reaction
H2SO4 and AlBr3 in an exothermic process because it causes energy to be released in reaction.
- Before performing any calculations, take note of the following:
- AlBr3 + H2SO4 = HBr + Al2(SO4)3
- The energy of the Element is mentioned
| Element | Energy in kJ/mol for element |
| AlBr3 | 56 |
| H2SO4 | -814 |
| Al2(SO4)3 | -3442 |
| HBr | -9.35 |
- Reactant = 56 kJ/mol + 814 kJ/mol = 870
- Product = -3442 kJ/mol + -9 kJ (g) = -3451
- Enthalpy= Product – reactant = -2581
- This is negative because it causes energy to be released, which causes an exothermic reaction.
Is H2SO4 and AlBr3 a redox reaction
H2SO4 and AlBr3 reaction is not a redox reaction. As shown in the equations:
+3 -1 +1 +6 -2 +3 +6 -2 +1 -1
2Al Br3 + 3H2 S O4 = Al2 (S O4)3 + 6H Br
Is H2SO4 and AlBr3 a precipitation reaction
H2SO4 and AlBr3 reaction is not a precipitation reaction because the hydrogen bromide gas that has been produced is being released.
Is H2SO4 and AlBr3 reversible or irreversible reaction
H2SO4 and AlBr3 is an irreversible reaction. As HBr is liberated from the product, the equilibrium cannot be moved backward.
Is H2SO4 and AlBr3 displacement reaction
H2SO4 and AlBr3 reaction is not a displacement reaction. Because one element from each compound was shifted to the other, the reaction between
Conclusion
The displacement reaction between Aluminum bromide, a weak acid, and sulphuric acid, a strong acid, resulted in the synthesis of Aluminum sulfate and the evolution of hydrogen bromide gas. The process is exothermic and produces energy. The reaction is also irreversible because the emission of HBr prevents the equilibrium from shifting.
