Preparation of Sulfuric Acid Solution in Test Tubes

To prepare a sulfuric acid (H₂SO₄) solution in test tubes, follow these steps:

1. Gather Materials: - 4 test tubes - Sulfuric acid (H₂SO₄) - Distilled water

2. Measure Sulfuric Acid: - Using a dropper or pipette, measure 1-2 ml of sulfuric acid and add it to each test tube. Sulfuric acid is a strong acid, so handle it with care and use appropriate safety measures.

3. Add Distilled Water: - After adding the sulfuric acid, carefully add an appropriate amount of distilled water to each test tube to achieve the desired dilution. The exact amount of water will depend on the concentration of the sulfuric acid and the desired final concentration of the solution.

4. Mix Thoroughly: - Use a stirring rod or pipette to mix the contents of each test tube thoroughly, ensuring that the sulfuric acid is evenly diluted in the water.

5. Label the Test Tubes: - It's important to label each test tube with the concentration of the sulfuric acid solution and any other relevant information for future reference.

6. Safety Precautions: - Always wear appropriate personal protective equipment, such as gloves and safety goggles, when handling sulfuric acid. Work in a well-ventilated area and follow all safety guidelines for handling corrosive substances.

Remember to handle sulfuric acid with caution and follow all safety protocols to ensure safe and accurate preparation of the solution.
