The answeres to the previous post was not what I am looking for...so please try to help me.....
How can I make various concentrations of CuSO4(this is a blue solution)?
I know that to make 0.1M you would fill the copper solution up to 10mL in the graduated cylinder and then add water to the rest..but how can you prepare a 0.01M? 0.001? 0.0001?..........using water and graduated cylinder?
To make various concentrations of CuSO4 solution, you will need to use a technique called serial dilution. Here's how you can prepare different concentrations using a graduated cylinder and water:
1. Start with a concentrated stock solution of CuSO4. Let's assume you have a 1M stock solution.
2. To prepare a 0.1M solution, you will need to dilute the stock solution by a factor of 10. Take 1 mL of the stock solution and add it to a graduated cylinder. Then, add water to make the total volume 10 mL.
3. To prepare a 0.01 M solution, you will need to dilute the 0.1M solution by another factor of 10. Take 1 mL of the 0.1M solution you prepared in the previous step and add it to another graduated cylinder. Add water to make the total volume 10 mL.
4. To prepare a 0.001M solution, you will need to dilute the 0.01M solution by another factor of 10. Take 1 mL of the 0.01M solution and add it to another graduated cylinder. Add water to make the total volume 10 mL.
5. Similarly, to prepare a 0.0001M solution, you will need to dilute the 0.001M solution by another factor of 10. Take 1 mL of the 0.001M solution and add it to another graduated cylinder. Add water to make the total volume 10 mL.
By following this serial dilution process, you can prepare various concentrations of CuSO4 solution using a graduated cylinder and water. Just remember to rinse the graduated cylinder with distilled water between each dilution to ensure accurate results.
