  2. Golden rain demonstration - Wikipedia

    en.wikipedia.org/wiki/Golden_rain_demonstration

    Golden rain demonstration is made by combining two colorless solutions, potassium iodide solution and Lead(II) nitrate solution at room temperature to form yellow precipitate. During the chemical reaction, golden particles gently drop from the top of Erlenmeyer flask to the bottom, similar to watching the rain through a window.

    Sodium hydroxide, potassium hydroxide, and ammonium hydroxide can be used to alkalize the permanganate solution, while a variety of reducing agents can be used, sugars being common. [ 1 ] [ 5 ] [ 8 ] A similar demonstration involves soaking paper in alkalized permanganate solution, which produces the same color changes as the paper is oxidized ...

    Acid Chloride Preparative Route for Nylon-6,10, which is often used in the nylon rope trick. The nylon rope trick is a scientific demonstration that illustrates some of the fundamental chemical principles of step-growth polymerization and provides students and other observers with a hands-on demonstration of the preparation of a synthetic polymer.

  7. Iodine clock reaction - Wikipedia

    en.wikipedia.org/wiki/Iodine_clock_reaction

    The iodine clock reaction is a classical chemical clock demonstration experiment to display chemical kinetics in action; it was discovered by Hans Heinrich Landolt in 1886. [1] The iodine clock reaction exists in several variations, which each involve iodine species ( iodide ion, free iodine, or iodate ion) and redox reagents in the presence of ...

  8. Stopped-flow - Wikipedia

    en.wikipedia.org/wiki/Stopped-flow

    The time required for this solution to pass from the mixing point to the observation point is known as dead time. The minimum injection volume will depend on the volume of the mixing cell. Once enough solution has been injected to completely remove the previous solution, the instrument reaches a stationary state and the flow can be stopped.

  9. Single-molecule experiment - Wikipedia

    en.wikipedia.org/wiki/Single-molecule_experiment

    A single-molecule experiment is an experiment that investigates the properties of individual molecules. Single-molecule studies may be contrasted with measurements on an ensemble or bulk collection of molecules, where the individual behavior of molecules cannot be distinguished, and only average characteristics can be measured.
