* The reaction produces magnesium sulfate, not crystals. The reaction between magnesium (Mg) and sulfuric acid (H₂SO₄) produces magnesium sulfate (MgSO₄) and hydrogen gas (H₂):
Mg(s) + H₂SO₄(aq) → MgSO₄(aq) + H₂(g)
* Magnesium sulfate is soluble in water. The magnesium sulfate produced is dissolved in the water of the sulfuric acid solution.
To obtain crystals of magnesium sulfate, you need to follow these steps:
1. Perform the reaction: React magnesium with sulfuric acid, ensuring the reaction is complete.
2. Evaporate the water: Carefully evaporate the water from the solution. This can be done using a hot plate or a water bath.
3. Crystallization: As the water evaporates, the concentration of magnesium sulfate increases, and crystals will start to form.
4. Separation and drying: Once the solution is mostly evaporated, you can separate the crystals from any remaining solution by filtration. Then, let the crystals dry thoroughly.
Important Safety Notes:
* This reaction produces hydrogen gas, which is flammable. Perform the experiment in a well-ventilated area and away from open flames.
* Sulfuric acid is corrosive. Wear appropriate safety gear, including gloves and eye protection, when handling it.
* Be careful when heating the solution. It could splash and cause burns.
