To determine which salt is produced when sulfuric acid (H₂SO₄) reacts with sodium hydroxide (NaOH), we can start by looking at the balanced chemical reaction between these two compounds.
1. Write the chemical equation for the reaction.
Sulfuric acid (H₂SO₄) reacts with sodium hydroxide (NaOH). The reaction is a double displacement reaction, where the hydroxide ions (OH⁻) from sodium hydroxide (NaOH) combine with the hydrogen ions (H⁺) from sulfuric acid (H₂SO₄) to form water (H₂O), and the remaining ions (sodium (Na⁺) and sulfate (SO₄²⁻)) form the salt.
The balanced chemical equation is:
[tex]\[
\text{H}_2\text{SO}_4 + 2 \text{NaOH} \rightarrow \text{Na}_2\text{SO}_4 + 2 \text{H}_2\text{O}
\][/tex]
2. Identify the products of the reaction.
- One product is water (H₂O), which is formed from the combination of hydrogen ions (H⁺) and hydroxide ions (OH⁻).
- The other product is the salt, formed from the sodium ions (Na⁺) and sulfate ions (SO₄²⁻).
3. Write down the formula of the salt.
The sodium ions (Na⁺) and sulfate ions (SO₄²⁻) combine to form sodium sulfate. The chemical formula for sodium sulfate is Na₂SO₄.
4. Review the given options to select the correct salt.
- K₂SO₃
- Na₂SO₄
- Na₂SO₃
- K₂SO₄
The correct salt produced in this reaction is Na₂SO₄.
Therefore, the answer to the question "Which salt is produced when H₂SO₄ reacts with NaOH?" is:
Na₂SO₄ (option 2).
