You are provided with a stock solution with a concentration of 1.0x10-5 M. You will be using this to make two standard solutions via serial dilution.
1. Perform calculations to determine the volume of the 1.0x10-5 M stock solution needed to prepare 10.0 mL of a 2.0x10-6 M solution. Perform calculations to determine the volume of the 2.0x10-6 M solution needed to prepare 10.0 mL of a 5.0x10-7 M solution. You are welcome to do the calculations in your notebook prior to lab.
2. Prepare 10.0 mL of a 2.0x10-6 M solution using a graduated cylinder. Transfer the solution to a clean 50 mL beaker.
3. Prepare 10.0 mL of a 5.0x10-7 M solution using a graduated cylinder. Transfer the solution to a clean 50 mL beaker.

"Prepare 500 mL of a 0.1 M sodium hydroxide solution by dilution of a 1 M sodium hydroxide stock reagent or from solid NaOH. This dilution need only be performed to 5% accuracy, that is, using a graduated cylinder and an Erlenmeyer flask." 1. Explain why it is not necessary and even not desirable to perform the preparation of 1 M sodium hydroxide operation with higher accuracy. "Add the analyte to the beaker and fill with distilled deionized water to...
