When sodium hydroxide (NaOH) reacts with sulfuric acid (H₂SO₄) in a complete neutralization reaction, the products formed are a salt and water. Let's carefully analyze this reaction step-by-step.
1. Balanced Chemical Equation:
- Sodium hydroxide is a strong base.
- Sulfuric acid is a strong acid.
- The balanced chemical equation for the reaction is:
[tex]\[
2 \text{NaOH} + \text{H}_2\text{SO}_4 \rightarrow \text{Na}_2\text{SO}_4 + 2\text{H}_2\text{O}
\][/tex]
2. Identifying the Salt:
- From the balanced equation, we can see that one molecule of sulfuric acid reacts with two molecules of sodium hydroxide.
- This reaction produces sodium sulfate (Na₂SO₄) as the salt, and water (H₂O).
3. Conclusion:
- The salt produced in the complete neutralization of sodium hydroxide with sulfuric acid is sodium sulfate.
- Its chemical formula is [tex]\( \text{Na}_2\text{SO}_4 \)[/tex].
Given the options:
1. [tex]\( \text{Na}_3\text{SO}_4 \)[/tex]
2. [tex]\( \text{Na}_2(\text{SO}_4)_3 \)[/tex]
3. [tex]\( \text{Na}_2\text{SO}_4 \)[/tex]
4. [tex]\( \text{Na}^{\prime}(\text{SO})_2 \)[/tex]
5. [tex]\( \text{NaSO}_3 \)[/tex]
The correct answer is:
[tex]\[ \text{Na}_2\text{SO}_4 \][/tex]
Thus, the chemical formula of the salt produced by the complete neutralization of sodium hydroxide with sulfuric acid is [tex]\( \text{Na}_2\text{SO}_4 \)[/tex].
