- Q: Can some one suggest chemical pigments that can be easily made from chemicals available in a chemistry lab for a project?I need the name of the pigment, reactants required and chemical equations of reactions involved.I need atleast 5 pigments
- Some pigments easy to make in a school laboratory: 1) Calcium carbonate: Mix solutions of calcium chloride and sodium carbonate : CaCl2(aq) + Na2CO3(aq) → CaCO3(s) + 2NaCl(aq) filter off and dry the calcium carbonate 2) Barium carbonate Exactly as above , but start with barium chloride 3) Calcium sulphate Mix solutions of calcium chloride and sodium sulphate: CaCl2(aq) + Na2SO4(aq) → CaSO4(s) + 2NaCl 4) Barium sulphate Use barium chloride instead of calcium chloride . 5) Satin white is another interesting pigment: Mix solutions of aluminium sulphate and calcium hydroxide with strong stirring , You get a paste which is a mixture of aluminium hydroxide and calcium sulphate . There is no specific formula because what you get depends on how you mix. Do not try and dry this out to get a dry pigment - it does not work. There are 5 white pigments that you can easily make - but remember to wear proper protective clothing when working with all chemicals
- Q: What does pigment mean?
- The natural coloring matter
- Q: what is the relationship between chlorophyll a, accessory pigment?
- Sativa- uplifting, high, trippy, baked out of your gourd, ****** up, spacy Indica- passing out, baked, stoned, sleepy, couchlock, retarded, weird dreams
- Q: are photosynthetic pigments separated based on their polarity or based on their molecular structure?Thanks
- Molecular structure... Chlorophylls are greenish pigments which contain a porphyrin ring. This is a stable ring-shaped molecule around which electrons are free to migrate. There are several kinds of chlorophyll, the most important being chlorophyll a. This is the molecule which makes photosynthesis possible, by passing its energized electrons on to molecules which will manufacture sugars. All plants, algae, and cyanobacteria which photosynthesize contain chlorophyll a. A second kind of chlorophyll is chlorophyll b, which occurs only in green algae and in the plants. A third form of chlorophyll which is common is (not surprisingly) called chlorophyll c, and is found only in the photosynthetic members of the Chromista as well as the dinoflagellates. The differences between the chlorophylls of these major groups was one of the first clues that they were not as closely related as previously thought. Carotenoids are usually red, orange, or yellow pigments, and include the familiar compound carotene, which gives carrots their color. These compounds are composed of two small six-carbon rings connected by a chain of carbon atoms. As a result, they do not dissolve in water, and must be attached to membranes within the cell. Carotenoids cannot transfer sunlight energy directly to the photosynthetic pathway, but must pass their absorbed energy to chlorophyll. For this reason, they are called accessory pigments. One very visible accessory pigment is fucoxanthin the brown pigment which colors kelps and other brown algae as well as the diatoms.
- Q: Explain why plants need a variety of pigments to carry out photosynthesis?
- In photosynthesis plants make their which is a carbohydrate i.e. a compound of carbon, hydrogen and oxygen. That carbohydrate is glucose (C6H12O6). The chemical equation of photosynthesis is : 6CO2 + 12H2O = C6H12O6 + 6O2 + 6H2O Here water, carbon dioxide and light (light gives the energy to prform the reaction) helps to form chains of carbohydrate that further makes sucrose, a type of sugar, which can be utilized by plants as food.
- 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?
- Pigment okorder /....
- Q: what are the differences between colorfast and non colorfast pigments?
- Pigments, are generally solids and are usually insoluble in the medium in which the pigment is being used. Pigments, are typically used instead of dyes in applications where color migration or bleeding is undesirable. One possible approach to create a colorfast pigment for use in something like toothpaste would be in a layered anion exchange material which is contacted with the dye under conditions in which a water-insoluble pigment is obtained. The water soluble dye and the layered anion exchange material would normally be contacted together in a liquid medium in which the dye has been dissolved. The layered anion exchange material is preferably a layered aluminate of some kind. Generally, pigments are graded by international standards for color fastness. Eight is the most color fast, and anything over six will do quite well out-of-doors. As ancient Frescoes, sand paintings, petroglyphs and other pure-pigment art demonstrate, certain pigments can remain in direct sunlight for thousands of years without any indication of fading. These pigments are earth, metal, and chemical colors that are neither dyes nor tints. Dyes and tints, such as alizarin crimson, berry juice, etc. will bleach quickly due to ultraviolet exposure that occurs in direct or indirect sunlight. Today most paints are derived from much different sources than they were as recently as fifty years ago. Real cadmium, cobalt, copper oxide, to name a few, are no longer used. They are now formulated to appear similar to the traditional pigments. They may be extended out with white, resulting in an appearance that can differ with traditional counterparts. For the most part these new colors are very colorfast and without the addition of medium or varnish they will not fade when left in direct sunlight.
- Q: i was thinking of this all day long and then i thought of posting this question for you to help me sort it out
- Pigments are chemicals inside living things that absorb certain types of light. In plants, the pigment chlorophyll in leaves absorbs sunlight for photosynthesis to work, where the energy comes from. Chlorophyll absorbs all light except green, which is reflected. That's why most plants are green. NOT the other war around. :) :)
- Q: light absorption, which pigments are involved?
- All photosynthetic organisms contain one or more organic pigments capable of absorbing visible radiation, which will initiate the photochemical reactions of photosynthesis. The three major classes of pigments found in plants and algae are the chlorophylls, the carotenoids and the phycobilins. Carotenoids and phycobilins are called accessory pigments since the quanta (packets of light) absorbed by these pigments can be transferred to chlorophyll. Chlorophylls chlorophyll a - present in all higher plants and algae chlorophyll b - present in all higher plants and green algae chlorophyll c - diatoms and brown algae chlorophyll d - red algae (chlorophyll a is present in all photosynthetic organisms that evolve O2.) Chlorophyll molecules contain a porphyrin 'head' and a phytol 'tail'. The polar (water-soluble) head is made up of a tetrapyrrole ring and a magnesium ion complexed with the nitrogen atoms of the ring. The phytol tail extends into the lipid layer of the thylakoid membrane. Carotenoids (carotenes and xanthophylls) Carotenes: -carotene - higher plants and most algae $-carotene - most plants some algae xanthophylls: luteol, fucoxanthol and violaxanthol Carotenoids contain a conjugated double bond system of the polyene type (C-C=C-C=C). Energy absorbed by carotenoids may be transferred to chlorophyll a for photosynthesis. Phycobilins (found mostly in red and blur-green algae): phycoerythrin phycocyanin allophycocyanin )
- Q: Many of the microorganisms found on environmental surfaces are pigmented. Of what possible advantage is the pigment?
- So they can absorb different light frequencies to use for energy (from photosynthesis). Light travels in water according to the frequency (wavelength). So different pigmented organisms are able to exist in different environments, possibly reducing competition with other forms.
