    To prepare a luminol solution, you will need the following materials:

    • Luminol powder
    • Sodium hydroxide (NaOH)
    • Hydrogen peroxide (H2O2)
    • Distilled water
    • A glass beaker or flask
    • A stirring rod or spoon
    • A spray bottle or dropper
    • A catalyst (optional)

    The steps to prepare a luminol solution are:

    1. Dissolve about 0.2 grams of luminol powder in 100 ml of distilled water in a glass beaker or flask.
    2. Add about 4 grams of sodium hydroxide to the solution and stir until it dissolves completely. The solution should have a pH of about 13.
    3. Add about 3 ml of hydrogen peroxide to the solution and stir well. The solution is now ready to use.
    4. If you want to enhance the brightness and duration of the glow, you can add a small amount of a catalyst, such as potassium ferricyanide (K3Fe(CN)6), copper sulfate (CuSO4), or iron sulfate (FeSO4). Be careful not to add too much catalyst, as it may cause the solution to overheat or explode.
    5. Pour the solution into a spray bottle or dropper and store it in a dark place until use.
