Describe how you would prepare 100ml of a solution that is 22% acetic acid by volume?
I am wondering from what solution you are starting. Glacial acetic acid is about 99.5 percent, so assuming that is the starting point, you are diluting it 99.5/22 times, or about 4.52 times, which means one part acid, 3.52 water. So what is one part?
one part=100ml/4.52=22.1 ml
so add 22.1 ml glacial acid to 3.52*22.1 ml=77.8 ml water.
Now, you can do it more accurately, added up, the above is 99.9ml short .1 ml.
But the point is, what are you starting with?
Always add acid to water.
To prepare a 100ml solution that is 22% acetic acid by volume, you will need to follow these steps:
1. Determine the amount of acetic acid required: Since we want a 22% solution, 22% of 100ml is 0.22 * 100 = 22ml.
2. Measure out 22ml of pure acetic acid. Using a graduated cylinder or pipette, carefully measure out 22ml of acetic acid.
3. Transfer the measured acetic acid to a 100ml volumetric flask. Pour the 22ml of acetic acid into a clean and dry 100ml volumetric flask.
4. Add distilled water to the flask. Slowly and carefully pour distilled water into the flask until the volume reaches the 100ml mark on the neck of the flask.
5. Mix thoroughly. Use a glass stirring rod or cap the flask securely and gently shake it to ensure thorough mixing of the acetic acid and water.
6. Label the flask. Indicate the contents of the flask (22% acetic acid solution) and any other relevant information such as the date of preparation.
Please note that acetic acid is a corrosive substance and should be handled with care. Use appropriate safety precautions, such as wearing gloves and goggles, and work in a well-ventilated area.
To prepare a 100ml solution that is 22% acetic acid by volume, you will need to follow these steps:
1. Determine the amount of acetic acid required: 22% of 100ml is 22ml. This means you need to have 22ml of acetic acid in the final solution.
2. Next, acquire pure acetic acid, which is often available in concentrated form (usually around 99-100% purity). Measure out 22ml of concentrated acetic acid using a graduated cylinder or a pipette.
3. Now, you need to dilute the concentrated acetic acid with a suitable solvent, such as water, to reach a total volume of 100ml. Transfer the 22ml of acetic acid to a clean and dry beaker.
4. Slowly add water to the beaker while continuously stirring until the final volume reaches 100ml. It is crucial to add the solvent slowly and stir well to ensure thorough mixing.
5. Once the solution reaches the desired volume of 100ml, you have successfully prepared a 22% acetic acid solution by volume. Remember to label the container with the appropriate information for future use.
Important note: Please be cautious when handling concentrated acetic acid, as it is corrosive and can cause irritation. Wear appropriate protective equipment, such as gloves and goggles, during the preparation process.
