Q:what are ten names of natural pigments to make paint?
Q:What are accesory pigments and why are they important?
Accessory pigments, also called, Photosynthetic Pigments or Chloroplast pigments, are pigments which are present within the cell of a Chloroplast used to harvest a greater spectrum of light.y are colored compounds which absorb and transfer light energy to chlorophyll. Pigments are light-absorbing molecules. In addition to chlorophyll,other pigments, principally yellow and orange carotenoids, as well asother forms of chlorophyll, are also present in green plants. These molecules absorb light and then pass the energy to the chlorophyll and accessory pigments, like the carotenoids, enable the plants to use more ofthe light than is trapped by chlorophyll alone.
Q:ive been watching a lot of makeup videos on youtube and a lot of the girls use mac pigments. what exactly are they and how are they different from regular eyeshadow? are they easier or more difficult to use?
they are a loose powder like consistency, and they're just that.. they're super pigmented!!! ut i have about 26 pigments (: most are mac, some other brands.
Q:How can you extract pure pigments from a sample of leaves in a form that you could test the absorbency of the various pigments??I don't know how to extract enough pigment in order to fill a cuvette and measure the absorbance, please help!! :D
Separation of plant pigments using chromatography. Paper chromatography is a useful technique in the separation and identification of different plant pigments. In this technique, the mixture containing the pigments to be separated is first applied as a spot or a line to the paper about 1.5 cm from the bottom edge of the paper. The paper is then placed in a container with the tip of the paper touching the solvent. Solvent is absorbed by the chromatographic paper and moved up the paper by capillary action. As the solvent crosses the area containing plant pigment extract, the pigments dissolve in and move with the solvent. The solvent carries the dissolved pigments as it moves up the paper. The pigments are carried along at different rates because they are not equally soluble. Therefore, the less soluble pigments will move slower up the paper than the more soluble pigments. This is known as developing a chromatogram.
Q:wut is the diff between those 2?
MAC pigment is a loose eyeshadow that comes in a jar. It is made with ingredients that help adhere to the skin it is also easy to blend and doesn't cake. It is also to use pigment if you want very intense colors. And MAC eyeshadow well it comes in a little case it is in powder form it's a lot easier to apply than the pigment because the pigment tends to get all over the place. Personally I like the eyeshadow better more shades and easier to apply.
Q:I need to know the classes and sub classes of pigments classification
INORGANIC PIGMENTS Oxides Chromates Sulphides Sulphoselenides Sulphates Silicates Ferrocyandies Carbonates Metallic Mixed Metal Oxides Vanadates ORGANIC PIGMENTS Organic pigments are generally categorized into six types : ?Monoazo Pigments ?Diazo Pigments ?Acid and base dye Pigments ?Phthalocyanine Pigments ?Quinacridone Pigments ?Other polycyclic Pigments if you want more detail: ORGANIC PIGMENTS: 1.AZO Pigments : Monoazo Yellow and Orange Pigments. Disazo Pigments. β-Naphthol Pigments. Naphthol AS Pigments (Naphthol Reds). Azo Pigment Lakes (Salt Type Pigments). Benzimidazolone Pigments. Disazo Condensation Pigments. Metal Complex Pigments. 2.POLYCYCLIC Pigments: Phthalocyanine Pigments. Quinacridone Pigments. Perylene and Perinone Pigments. Diketopyrrolo–Pyrrole (DPP) Pigments. Thioindigo Pigments. Isoindolinone and Isoindoline Pigments. 3. Anthraquinone Pigments. Anthrapyrimidine Pigments. Flavanthrone Pigments. Pyranthrone Pigments. Anthanthrone Pigments. 4. Dioxazine Pigments. Triarylcarbonium Pigments. Quinophthalone Pigments
Q:This has to do with photosynthesis
Q:thank you very much for your help!
Well photosynthetic pigments has to do with the different component of light (i.e. the colors - ROYGBIV) and their specific wavelenght. Photosynthetic pigments based on their colors can capture the energy from that wavelenght. For example fucoxanthin can capture the brown color of the light just like phycocyanin can capture the blue color of the light. These photosynthetic pigments are usually the accessory pigments of Chlorophyll A which is the main pigments of most of the photosynthetic organisms in the earth.
Q:What does it mean when something is highly pigmented?
PIGMENTED = A HIGH SATURATION OF COLOUR
Q:what is the pigment in hibiscus?
Hibiscus flowers bear pigments of three types: carotenoids, anthocyanins, and flavonols. The exact pigments (all three of those types are actually sizeable families of similar chemicals) and the exact proportions depend on the color of the particular flower: there are literally several hundred species in the genus Hibiscus, and they come in all shades of red, pink, yellow, and orange. Carotenoids are oil-soluble, fairly stable pigments that come in all shades of red, orange, and yellow. Anthocyanins are water-soluble and significantly less stable: they're responsible for the blues, pinks, purples, and reds, and in high concentrations can produce colors so dark as to look black. Flavonols are the least vivid of the pigments: they produce pale pastel yellows, cream colors, and off-whites. (Plain white flowers usually have no visible pigment at all.) Flavonols actually do most of their color absorption in the UV spectrum: they're the plant equivalent of the melanin in human skin, keeping them from getting sunburnt.
Sinotio2, high technique enterprise with titanium series products production,scientific research and self distribution,the first and the only in china. It has titanium dioxide production line through chloride process which is the only line in mainland of China,and which has its self owned patents,The own line broke the technique blockade of the developed countries and promoted the development of Chinese titanium dioxide business.
