How To Obtain Ammonia From Ammonium Sulfate

Introduction

Ammonium sulfate is a common fertilizer used in agriculture. It is made by reacting sulfuric acid with ammonia. However, it is also possible to obtain ammonia from ammonium sulfate. In this tutorial, we will show you how to do this.

Materials

To obtain ammonia from ammonium sulfate, you will need the following materials:

• Ammonium sulfate
• Sodium hydroxide
• Bunsen burner
• Distillation apparatus
• Ice bath

Procedure

Follow these steps to obtain ammonia from ammonium sulfate:

1. Dissolve ammonium sulfate in water to make a solution.
2. Add sodium hydroxide to the solution to raise the pH to about 9.
3. Heat the solution using a Bunsen burner until it boils.
4. Collect the ammonia gas that is produced by distilling the solution.
5. Pass the ammonia gas through an ice bath to condense it into a liquid.
6. Collect the liquid ammonia in a container.

Explanation

When ammonium sulfate is dissolved in water and treated with sodium hydroxide, it undergoes a process called alkaline hydrolysis. This produces ammonia gas, which can be collected using distillation. By passing the gas through an ice bath, the ammonia is condensed into a liquid form that can be collected and used.

Uses of Ammonia

Ammonia has many uses, including:

• As a fertilizer in agriculture
• As a refrigerant in industrial applications
• As a cleaning agent in household and industrial cleaning products
• As a feedstock for the production of other chemicals

Safety Precautions

When working with chemicals, it is important to take proper safety precautions. When obtaining ammonia from ammonium sulfate, be sure to:

• Work in a well-ventilated area
• Wear protective clothing, including gloves and safety glasses
• Handle chemicals with care and follow all instructions carefully
• Dispose of chemicals properly

Conclusion

Obtaining ammonia from ammonium sulfate is a simple process that can be done with basic laboratory equipment. Ammonia has many uses and is an important chemical in many industries. By following proper safety precautions, you can safely and easily obtain ammonia for your own use.
