How to make 80 acetone solution? Detailed step analysis

in chemical laboratory and industrial production, acetone solution as a common solvent, widely used in cleaning, extraction and other processes. When we need to prepare a certain concentration of acetone solution, it is particularly important to understand how to make 80 acetone solution. This article will introduce in detail how to make 80 acetone solution, and provide the materials, steps and precautions required in the production process.

1. Definition of 80 acetone solution

it is important to understand the concept of "80 acetone solution. 80 acetone solution means that the mass fraction of acetone in the solution is 80%, that is, every 100 grams of solution contains 80 grams of acetone, and the remaining 20 grams are solvent (usually water or other solvents). This concentration of acetone solution is commonly used in laboratory cleaning, dissolving certain chemicals and other occasions.

2. Material required for making 80 acetone solution

when making 80 acetone solution, you first need to prepare the following materials:

• acetone: The common anhydrous acetone on the market can be, acetone should have high purity, to avoid impurities affect the experimental results.
• Solvent: If the concentration of acetone is to be reduced to 80%, an appropriate amount of water or other suitable solvents need to be added.
• Measuring cylinder or pipette: Used to accurately measure acetone and solvent.
• Agitator: Ensure that the solution is fully mixed to achieve uniformity.

3. How to calculate the ratio of acetone and solvent

when making an 80 acetone solution, the correct ratio is essential. We need to determine the total amount of solution needed. Suppose we want to make 1000 ml of 80 acetone solution. According to the mass fraction, the mass of acetone in the solution should be 80% (I .e. 800 ml of acetone), and the rest should be solvent (200 ml). Special attention should be paid here to the fact that acetone has a density of 0.79 g/mL, so 800 ml of acetone is about 632g, while 200 ml of solvent needs to be ensured to have the correct mass ratio to acetone.

4. Specific operation steps

the operation steps for making 80 acetone solution are as follows:

1. take acetone: According to the volume of the required solution, measure the appropriate amount of acetone with a measuring cylinder or pipette. Assuming the target is 1000 ml of 80 acetone solution, measure 800 ml of acetone.
2. Measuring solvent: According to the proportion of acetone required, measure the corresponding amount of solvent. Like 200 milliliters of water.
3. mixed solution: Mix acetone and solvent together, use a stirrer or glass rod to stir evenly to ensure that the two are completely integrated.
4. Check the concentration: You can use a concentration meter to check whether the concentration of the solution meets the requirement of 80%. If the concentration is insufficient, add acetone and stir again.

5. Precautions

when making 80 acetone solution, you need to pay attention to the following points:

• accurate measure: To ensure that the proportion of acetone and solvent is accurate, to avoid the concentration of unqualified and affect the experiment or production.
• Solubility: Acetone has good solubility and is easy to mix with water or other solvents, but pay attention to the strong volatility of acetone, and avoid excessive exposure of the solution to the air.
• Operating Environment: Acetone is a flammable liquid. The operation should be carried out in a well-ventilated place to avoid fire and high temperature.

6. Frequently Asked Questions

how to check the concentration of 80 acetone solution? It is possible to ensure that the acetone content of the solution meets the 80% standard by density measurement or concentration testing using a chemical kit.

If acetone concentration is too high, how to adjust? If the concentration of acetone exceeds 80%, appropriate amount of solvent can be added to dilute, and the test can be carried out after stirring evenly.

Conclusion

through the above steps, you have learned how to make 80 acetone solution. Mastering this technology can not only ensure the smooth progress of the experimental process, but also help you accurately control the concentration of acetone solution in industrial production. Keeping in mind the details of the operation, safety and accuracy are always the key to making high-quality solutions.
