    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.

  3. Color of water - Wikipedia

    en.wikipedia.org/wiki/Color_of_water

    Water molecules can vibrate in three different modes when they interact with light. The red, orange, and yellow wavelengths of light are absorbed so the remaining light seen is composed of green, cyan, and blue wavelengths. This is the main reason the ocean's color is cyan. The relative contribution of reflected skylight and the light scattered ...

    [1] [2] The solid formed is called the precipitate. [3] In case of an inorganic chemical reaction leading to precipitation, the chemical reagent causing the solid to form is called the precipitant. [4] The clear liquid remaining above the precipitated or the centrifuged solid phase is also called the supernate or supernatant.

    Diamond as a form of carbon is tasteless, odourless, strong, brittle solid, colourless in pure form, a poor conductor of electricity, and insoluble in water. Another solid form of carbon known as graphite is the chemically stable form of carbon at room temperature and pressure, but diamond is metastable and converts to it at a negligible rate ...

    Cobalt chloride is pink or blue depending on the state of hydration (blue dry, pink with water) so it is used as a moisture indicator in silica gel. Zinc oxide is white, but at higher temperatures becomes yellow, returning to white as it cools.

  7. Chromophore - Wikipedia

    en.wikipedia.org/wiki/Chromophore

    In biological molecules that serve to capture or detect light energy, the chromophore is the moiety that causes a conformational change in the molecule when hit by light. Healthy plants are perceived as green because chlorophyll absorbs mainly the blue and red wavelengths but green light, reflected by plant structures like cell walls, is less ...

    en.wikipedia.org/wiki/Beryl

    The word beryl – Middle English: beril – is borrowed, via Old French: beryl and Latin: beryllus, from Ancient Greek βήρυλλος bḗryllos, which referred to a 'precious blue-green color-of-sea-water stone'; [2] from Prakrit veruḷiya, veḷuriya 'beryl' [8] [a] which is ultimately of Dravidian origin, maybe from the name of Belur or ...

    Fluorine condenses to a pale yellow liquid at −188.11 °C and freezes into a colourless solid [5] at −219.67 °C. The solid form (density 1.7 g/cm −3) has a cubic crystalline structure and is soft and easily crushed. Fluorine is an insulator in all of its forms.
