Here's the balanced chemical equation:
Na₂CO₃ + H₂SO₄ → Na₂SO₄ + CO₂ + H₂O
Explanation:
* Sodium carbonate is a basic compound, while hydrogen sulfate is a strong acid.
* The reaction is an acid-base reaction (neutralization reaction).
* The hydrogen ions (H⁺) from the sulfuric acid react with the carbonate ions (CO₃²⁻) from sodium carbonate.
* This reaction produces carbon dioxide gas (CO₂) which bubbles out, and water (H₂O).
* The remaining ions, sodium (Na⁺) and sulfate (SO₄²⁻), combine to form sodium sulfate (Na₂SO₄), which remains in solution.
Key Observations:
* Bubbling: You will observe the release of carbon dioxide gas as bubbles.
* Heat generation: The reaction is exothermic, meaning it releases heat.
* Change in pH: The initial solution of sulfuric acid would be acidic, but after the reaction, the pH will increase as the acid is neutralized.
Safety Precautions:
* Sulfuric acid is a corrosive acid. Wear appropriate safety gear, such as gloves and goggles, when handling it.
* The reaction generates heat, so handle the mixture carefully.
* Do the reaction in a well-ventilated area as carbon dioxide gas can be dangerous in high concentrations.
