Question

Predict which test tube (A, B, or C) will glow the longest. Briefly explain your reasoning.

For test tube (A)- In a small beaker, dilute 5 mL of the luminol solution with 10 mL of distilled water. Add 5 mL of this diluted luminol solution to a test tube. Add 5 mL of the copper(II) solution to the solution and mix. Obtain 5 ml of the peroxide solution in a graduated cylinder. Turn off the light in the hood and add the 5 mL of peroxide solution to the test tube. Time how long the solution glows and record the information in your lab notebook. For test tube (B) - Dilute 5 mL of the luminol solution with 5 mL of distilled water (Note: you should turn the light back on while you are mixing solutions). Add 5 mL of this diluted luminol solution to a new test tube. Add 5 mL of the copper(II) solution to the solution and mix. Again, obtain 5 ml of the peroxide solution in a graduated cylinder. Turn off the light in the hood and add the 5 mL of peroxide solution to the test tube. Time how long the solution in this test tube glows and record the information in your lab

notebook. Comment on how the time and strength of the glow compares to the solution in the first test tube. For test tube (C)- Add 5 mL of the undiluted luminol solution to a third test tube. Add 5 mL of the copper(II) solution to the solution and mix. Again, obtain 5 ml of the peroxide solution in a graduated cylinder. Turn off the light in the hood and add the 5 mL of peroxide solution to the test tube. Time how long the solution in this test tube glows and record the information in your lab notebook. Record your observations again.
