A student requires 2.00 L of 0.100 M NH4NO3 for an upcoming experiment. This particular chemical compound, ammonium nitrate, is widely used in various scientific applications, including agricultural fertilizers, as well as in the production of explosives and rocket propellants. In this article, we will explore the significance of this compound, the process of preparing the required solution, and the precautions that need to be taken while handling it.
Ammonium nitrate, with the chemical formula NH4NO3, is a white crystalline solid that is highly soluble in water. It is composed of one ammonium ion (NH4+) and one nitrate ion (NO3-). The compound is known for its high nitrogen content, which makes it an excellent fertilizer for crops. Additionally, its explosive properties have made it a key ingredient in the production of explosives and rocket propellants.
To prepare the required 2.00 L of 0.100 M NH4NO3 solution, the student will need to follow a few steps. First, calculate the amount of NH4NO3 needed using the formula:
Moles of solute = Molarity × Volume (in liters)
In this case, the moles of NH4NO3 required will be:
Moles of NH4NO3 = 0.100 M × 2.00 L = 0.200 moles
Next, determine the mass of NH4NO3 needed using its molar mass, which is approximately 80.04 g/mol:
Mass of NH4NO3 = Moles of NH4NO3 × Molar mass = 0.200 moles × 80.04 g/mol = 16.008 g
Once the required amount of NH4NO3 is obtained, the student should dissolve it in a small amount of water to ensure complete dissolution. Then, transfer the solution to a volumetric flask and add water to the mark to reach the desired volume of 2.00 L.
It is crucial to handle NH4NO3 with care due to its potential hazards. The compound can decompose at high temperatures, releasing toxic nitrogen oxides and oxygen. Therefore, it is essential to store NH4NO3 in a cool, dry place away from direct sunlight and heat sources. Moreover, avoid mixing it with organic materials or reducing agents, as these can increase the risk of an explosion.
In conclusion, a student requires 2.00 L of 0.100 M NH4NO3 for an experiment, and this compound has a wide range of applications in science and industry. By following the proper procedures for preparation and handling, the student can ensure a safe and successful experiment.
