Write the balanced chemical equation for the neutralization reaction that occurs when an aqueous solution of hydrobromic acid (HBr) is mixed with an aqueous solution of lithium hydroxide (LiOH). Indicate the physical states of the reactants and products using the abbreviations (s), (l), (g), or (aq) for solids, liquids, gases, or aqueous solutions, respectively.

Express your answer as a chemical equation.



Answer :

Sure, let's go through the step-by-step process of writing the balanced chemical equation for the neutralization reaction between hydrobromic acid (HBr) and lithium hydroxide (LiOH).

1. Identify the reactants and products:
- The reactants are:
- Hydrobromic acid (HBr) in aqueous solution.
- Lithium hydroxide (LiOH) in aqueous solution.
- The products of a neutralization reaction (acid + base) are:
- Water (H₂O).
- A salt, which in this case is lithium bromide (LiBr) in aqueous solution.

2. Write the unbalanced chemical equation:
[tex]\[ \text{HBr(aq) + LiOH(aq)} \][/tex]

3. Predict the products based on the reactants:
- The hydrogen ion (H⁺) from the acid (HBr) will combine with the hydroxide ion (OH⁻) from the base (LiOH) to form water (H₂O).
- The remaining ions, lithium (Li⁺) from LiOH and bromide (Br⁻) from HBr, will combine to form lithium bromide (LiBr).

4. Combine the ions to form the products:
[tex]\[ \text{LiBr(aq) + H₂O(l)} \][/tex]

5. Balance the chemical equation:
- Check that the number of atoms of each element is the same on both sides of the equation.
- In this case, the equation is already balanced, with 1 hydrogen (H), 1 bromine (Br), 1 lithium (Li), and 1 oxygen (O) on both sides.

6. Indicate the physical states of the reactants and products:
- HBr is an aqueous solution: HBr(aq).
- LiOH is an aqueous solution: LiOH(aq).
- LiBr (lithium bromide) will be in aqueous solution: LiBr(aq).
- Water (H₂O) is a liquid: H₂O(l).

Therefore, the balanced chemical equation for the neutralization reaction is:

[tex]\[ \text{HBr(aq) + LiOH(aq) -> LiBr(aq) + H₂O(l)} \][/tex]
