Making 98% Concentrated Sulfuric Acid from Epsom Salt - DIY

Introduction

In this tutorial, we will learn how to synthesize 98% concentrated sulfuric acid using Epsom salt, also known as magnesium sulfate. This DIY chemistry project is suitable for enthusiasts looking to deepen their understanding of chemical reactions and practical applications. Follow these steps carefully to ensure safety and success in your experiment.

Step 1: Gather Necessary Materials

Before starting the synthesis, make sure you have the following materials ready:

• Epsom salt (magnesium sulfate)
• A heat source (e.g., a Bunsen burner or a hot plate)
• A glass container or beaker
• A thermometer
• Safety gear (gloves, goggles, and lab coat)
• Distilled water
• A desiccator or drying agent (like anhydrous magnesium sulfate or silica gel)

Tips

• Work in a well-ventilated area to avoid inhaling fumes.
• Always wear appropriate safety gear to protect yourself from spills and splashes.

Step 2: Prepare the Epsom Salt

1. Measure out the desired amount of Epsom salt. A common starting point is 100 grams.
2. Place the Epsom salt into the glass container.

Practical Advice

• Ensure the glass container is heat-resistant to withstand high temperatures.

Step 3: Heat the Epsom Salt

1. Place the glass container on the heat source.
2. Gradually heat the Epsom salt while monitoring the temperature with the thermometer.

Important Points

• The goal is to dehydrate the Epsom salt, removing water molecules and converting it into magnesium oxide and sulfur trioxide.
• Keep an eye on the temperature to prevent overheating, which can lead to unwanted reactions.

Step 4: Collect the Sulfuric Acid

1. As the Epsom salt heats, it will decompose and release sulfur trioxide gas.
2. Capture the gas using a suitable method, such as passing it through a container filled with distilled water to form sulfuric acid.

Common Pitfalls

• Avoid letting the gas escape. Make sure your setup is airtight to maximize yield.
• Be cautious with the generated heat and fumes, as they can be hazardous.

Step 5: Purify the Sulfuric Acid

1. Once you have collected the sulfuric acid, transfer it to a desiccator or use a drying agent to remove any residual moisture.
2. Ensure the acid reaches a concentration of approximately 98% for optimal use.

Real-World Applications

• The concentrated sulfuric acid can be used in various applications, including battery production, chemical synthesis, and as a dehydrating agent.

Conclusion

You have now successfully synthesized 98% concentrated sulfuric acid from Epsom salt. Always remember to handle chemicals with care and follow safety protocols.
