Last one. Describe how you would prepare 100ml of a solution that is 22% acetic acid by volume?
Add 22 mL of acetic acid (100% stuff) to enough water to make a total volume of 100 mL. You may not have 100% stuff in which case you will need to determine the volume of what you have to obtain 22 mL acetic acid
To prepare 100ml of a solution that is 22% acetic acid by volume, you would need to follow these steps:
1. Determine the amount of acetic acid needed: A 22% acetic acid solution means that 22ml of acetic acid is present in every 100ml of solution. So, for a 100ml solution, you would need 22ml of acetic acid.
2. Obtain the necessary materials: You will need a container to hold the solution, a measuring cylinder or pipette to measure the acetic acid, and a source of acetic acid (e.g., concentrated acetic acid vinegar).
3. Measure the acetic acid: Using a measuring cylinder or pipette, carefully measure 22ml of acetic acid, making sure to follow the appropriate safety precautions and handling procedures.
4. Transfer the acetic acid: Pour the measured 22ml of acetic acid into the container that will hold the final solution.
5. Dilute with water: Add enough distilled water to the container to bring the total volume of the solution up to 100ml. This can be achieved by using a graduated cylinder to measure the required amount of water.
6. Mix well: Gently stir or swirl the container to ensure that the acetic acid and water are thoroughly mixed.
7. Label the solution: Finally, label the container with appropriate information including the concentration (22% acetic acid) and the date of preparation.
By following these steps, you will be able to prepare a 100ml solution that is 22% acetic acid by volume.
