Preparation of 0.1M H2SO4 Solution for 100ml
Introduction
Sulfuric acid (H2SO4) is a strong acid widely used in various industries, including laboratory applications. In this article, we will discuss the preparation of 0.1M H2SO4 solution for 100ml.
Materials Needed
- Sulfuric acid (H2SO4) with a concentration of 18M or 98% (depending on the stock solution available)
- Distilled water
- Volumetric flask (100ml)
- Pipette or measuring cylinder
- Gloves and goggles for safety precautions
Preparation Steps
Step 1: Calculate the Volume of H2SO4 Required
To prepare 0.1M H2SO4 solution, we need to calculate the volume of H2SO4 required. The molarity of the stock solution is given as 18M or 98%.
Let's assume we have a 18M H2SO4 stock solution. To calculate the volume of H2SO4 required, we can use the following formula:
Volume of H2SO4 = (Molarity of desired solution x Volume of solution) / Molarity of stock solution
Volume of H2SO4 = (0.1M x 100ml) / 18M Volume of H2SO4 = 0.56ml
Step 2: Pipette the Required Volume of H2SO4
Using a pipette or measuring cylinder, accurately measure and transfer 0.56ml of H2SO4 into a 100ml volumetric flask.
Step 3: Add Distilled Water
Slowly add distilled water to the volumetric flask while gently swirling the mixture. Add water until the volume reaches the 100ml mark.
Step 4: Mix Well and Label
Mix the solution well by gentle swirling or inversion of the flask. Label the flask with the solution details, including the molarity, volume, and date of preparation.
Safety Precautions
When handling sulfuric acid, it is essential to take necessary safety precautions to avoid accidents and exposure. Wear protective gloves, goggles, and a lab coat to prevent skin and eye contact. Handle the solution in a well-ventilated area and avoid inhalation of the acid fumes.
Conclusion
The preparation of 0.1M H2SO4 solution for 100ml is a straightforward process that requires careful calculation and handling of the acid. By following these steps and taking necessary safety precautions, you can successfully prepare this solution for your laboratory applications.
