  • Phosphates In Water Pollution

    1063 words, 5 pages

    Phosphates may be created by substituting some or all of the hydrogen of a phosphoric acid by metals. Depending on the number of hydrogen atoms that are replaced, the resulting compound is described as a primary, secondary or tertiary phosphate. Primary and secondary phosphates contain hydrogen and are acid salts. Secondary and tertiary phosphates, with the exception of those of sodium, potassium and ammonium are insoluble in water. Tertiary sodium phosphate is valuable as a detergent and water softener. The primary phosphates t

    Examine The Value Of Colour In Everyday Life

    1184 words, 5 pages

    Colour provides us with the ability to differentiate many things. The value of colour is so extensive. It ranges from the use of language to artists and designing. There are a variety of examples that require the existence of colour and without it, these things will just be boring. Television has moved from black and white to coloured. Without us realizing, black and white are also colours. They are just duller version of colours and are often not considered as colours. In my argument, I will be discussing about the various uses of colour in everyday life from the simplest objects to different

    Dyes & Pigments Industry Export-led demand and marginal growth in the domestic textiles sector and other sectors like paper and leather is expected to result in 6 per cent growth in 2008-09. According to the industry sources, the domestic dyestuffs industry plans to target export turnover of $2 billion by the year 2010-11 from the current export volume of $1.3 billion in 2007-08, raising its global market share from 6% to 10%. Though exports of value added pigments and reactive dyes will increase, movements in the currency is likely to affect realizations. Raw ma

    Photosynthesis

    1002 words, 5 pages

    Photosynthesis uses light energy and carbon dioxide to make triose phospates (G3P). G3P is generally considered the prime end-product of photosynthesis. It can be used as an immediate food nutrient, or combined and rearranged to form disaccharide sugars, such as sucrose and fructose, which can be transported to other cells, or packaged for storage as insoluble polysaccharides such as starch. A commonly used but slightly simplified equation for photosynthesis is: 6 CO2(gas) + 12 H2O(liquid) + photons ? C6H12O6(aqueous) + 6 O2(gas) + 6 H2O(liquid) carbon dioxide +

    Phenylketonuria

    1238 words, 5 pages

    Phenylketonuria is a rare congenital genetic disease in which a baby is born and lacks the ability to break down the certain amino acid phenylalanine. These few babies do not possess the gene that allows them to produce the enzyme called phenylalanine hydroxylase which is needed to break down the essential amino acid called phenylalanine. Phenylalanine is found in foods that contain protein, which most people do consume throughout their life, so this ability to process it would be extremely necessary, as it is hard to avoid a diet that contains some sort of protein. Without the enzyme to brea

    Dye Project: Johannes Itten Color Circle

    1181 words, 5 pages

    In creating the Johannes Itten color circle, the type of dye used is acid dye. The primary colors which are red, blue, and yellow were made with the acid dye. The secondary colors are orange, green, and violet. In order to make orange, yellow and red were mixed together. The green was made with blue and yellow mixed together. Violet was made with red and blue mixed together. The tertiary colors are red-orange, yellow-orange, yellow-green, blue- green, blue- violet, and red- violet. In making red- orange, more red was added to the orange. In making yellow- orange, there was more yellow added to

    Copper (Ii) Sulfate: An Inorganic Salt

    1506 words, 7 pages

    Copper (II) sulfate is an inorganic salt with the formula CuSO4. This salt exists as a series of compounds that differ in hydration. The anhydrous form is a pale green/gray-white powder, whereas the pentahydrate (CuSO4•5H2O), the most commonly encountered salt and the salt that was used in this lab, is bright blue. A pentahydrate means that five water molecules attached copper (II) sulfate within a hydrate. Copper (II) sulfate is a bright shade of blue, and very toxic to the environment, irritating to the eyes and skin, and also can cause damaging effects if swallowed. The lab involved calcula

    Organic Chemistry 12A Isolation of Chlorophyll and Carotenoid Pigments from Spinach Purpose The purpose of this experiment was to isolate ß-carotene, chlorophyll-A, and chlorophyll-B from spinach using column chromatography. Spinach was dehydrated using ethanol, and the pigments were extracted with dichloromethane. The spinach extracts were dried using CaCl2. Then, the solid pigments were run through a column using a non-polar solvent, hexane. The polar absorbent material in the column separated the different pigments by allowing the least polar molecules to travel through the column f

    Determination Of Acetic Acid In Vinegar Using A Ph Electrode

    1500 words, 6 pages

    In the first investigation of the lab, the objective was to take the different household items and determine the pH of each of them. In investigation two, the objective was to use acetic acid in distilled white vinegar and find the percent composition of it. In the first investigation of the laboratory, it was important to find whether the household items were basic or acidic. To continue through the experiment, a temperature probe and pH electrode was used. It would be classified as a base, if the number given by the probe was higher than seven. It is considered an acid, if the number given b

    Photosynthetic Pigments

    1510 words, 7 pages

    By: Paige Meinke Photosynthetic pigments are pigments that reflect and absorb different ranges of visible light. The reflection of light gives the pigments their color. Photosynthetic pigments are found in autotrophs, which are organisms that use light energy to make their own food in a process called photosynthesis. Some examples of autotrophs are plants, algae, and cyanobacteria [ (Speer) ]. There are many different photosynthetic pigments in each of these that play a part in photosynthesis, but the most common pigments are chlorophyll “a” & “b”, phycocyanin, phy
