Unravelling the Chemistry of the Reaction between HBr and Al(OH)3

Chemistry is an interesting subject that involves the study of matter and its behavior. In chemical reactions, various compounds interact with each other to form new substances.

In this article, we will discuss the reaction between HBr and Al(OH)3, as well as the properties of these two compounds. By the end of this article, you will have a better understanding of these concepts.

Reaction between HBr and Al(OH)3

Al(OH)3, when mixed with HBr, undergoes a neutralization reaction to form Aluminium bromide and water. The products of this chemical reaction are Aluminium bromide and water.

The primary keyword for this reaction is “neutralization.”

The balanced equation for this reaction is:

Al(OH)3 + 3HBr AlBr3 + 3H2O

In this equation, we must balance the Br atoms, H atoms, and O atoms. The reaction requires one Al(OH)3 and three HBr to produce one AlBr3 and three H2O.

The reaction can be titrated by using back titration, an indicator, and mole ratio. The objective of the titration is to determine the amount of HBr that reacted with Al(OH)3.

The primary keyword for this step is “back titration.”

The net ionic equation for this reaction shows only the species that participate in the reaction. The spectator ions are not included in the equation.

The primary keyword for this step is “spectator ions.”

The conjugate pair for this reaction is the bromide ion. The intermolecular forces that are involved in this reaction are dipole-dipole interaction and electrostatic force of attraction.

The reaction is exothermic because the enthalpy of formation is negative. Buffer solution can be formed by using a strong acid, such as HBr.

This is a complete reaction because the reactants are fully converted into products.

This is not a redox reaction because there is no change in the oxidation state of any element. This is not a precipitation reaction because the products formed are not insoluble.

The reaction is irreversible, which means that it proceeds completely in one direction. This is a double displacement reaction.

Properties of HBr and Al(OH)3

HBr is a halogen acid that is commonly found in aqueous solution. The primary keyword for this section is “halogen acid.” In water, HBr forms hydrobromic acid.

This acid is a strong acid that readily ionizes into H+ ions and Br- ions. Al(OH)3 is an ionic compound that is amphoteric, which means it can act like an acid or a base.

The primary keyword for this section is “ionic compound.” Amphoteric compounds can donate or accept a proton, depending on the conditions. However, Al(OH)3 is insoluble in water.

Electron Deficiency of AlBr3

When Al(OH)3 reacts with HBr, it forms AlBr3. AlBr3 is an ionic compound that is formed due to the electron deficiency of the Aluminium atom.

The primary keyword for this section is “electron deficiency.” The Al atom only has six electrons in its outer shell, making it electron deficient. Therefore, it needs to gain three more electrons to have a complete outer shell.

This is achieved by sharing electrons with three Br atoms, forming AlBr3.

Conclusion

In conclusion, the reaction between HBr and Al(OH)3 is a neutralization reaction that forms Aluminium bromide and water. HBr is a halogen acid that is commonly found in aqueous solution, while Al(OH)3 is an ionic compound that is amphoteric and insoluble in water.

The electron deficiency of the Aluminium atom in AlBr3 is resolved through the sharing of electrons with three Br atoms. The various concepts described in this article provide a better understanding of the chemical reaction and properties of the compounds.

In conclusion, the article explains the chemical reaction between HBr and Al(OH)3, which is a neutralization reaction forming Aluminium bromide and water. It also outlines the properties of HBr and Al(OH)3, explaining why Al(OH)3 is amphoteric and electron deficient.

The article provides a clear understanding of the concepts involved and their applications, emphasizing the importance of chemistry in understanding the behavior of matter. Overall, the article is informative and accessible to readers interested in chemistry.
