When you think of the word "drug" what comes to mind? Probably marijuana‚ cocaine‚ lsd‚ prescriptions but what about bath salts? When I first heard stories about people on bath salts my reaction was you have to be kidding right‚ but no first popping onto the radar of the DEA and poison control in 2010‚ this product is causing quite a stir in the United States. Mark Ryan from the LA poison control says in an interview on the Dr. Oz television show "that he has never seen a drug that has caused the

Photosynthesis Lab Report Purpose: To research the effect of different wavelengths (colors) of light on plant growth during photosynthesis. Background Information: Photosynthesis is the process by which sunlight is captured by chloroplasts within plant cells and turned into energy. This energy is used to help the plant grow roots‚ leaves‚ flowers and fruit. Energy is required by living things

mechanism since no chemical identity had been changed. The lab demonstrates the use of chemical molecular behavior to isolate a particular set of molecules. Caffeine had already existed in the leaf itself but needed to be separated from the other chemicals. Caffeine’s chemical structure is relatively similar to the nucleic acid purine in that they use nitrogen and is bicyclic but lacks an alkene‚ amine and an amide. Caffeine has a solubility of 67.0 g/100 mL in boiling water but tannins also boil in

CHEMISTRY LAB REPORTS How to Write a Lab Report Lab Reports gives the explanation of the experiment done Lab reports are an essential part of all laboratory courses and usually a significant part of your grade. If your instructor gives you an outline for how to write a lab report‚ use that. Here ’s a format for a lab report you can use if you aren ’t sure what to write or need an explanation of what to include in the different parts of the report. A lab report is how you explain what you did

Carbohydrate Lab Report Introduction Qualitative identification of a substance is of significant importance in chemistry. Physical constants such as melting points have traditionally been used by organic chemistry for identification of unknown compounds. As for inorganic substances‚ the precipitation of a solid‚ results of a flame test‚ or the formation of a colored substance could all be keys to identifying a sample. Chromatography and spectra are amongst the newer techniques

Solubility refers to the maximum amount of solute that dissolves in a given amount of solvent at a particular temperature Factors Affecting Solubility 1. Effect of Temperature For some substances to dissolve in a given solvent‚ heat is absorbed. The reaction is endothermic. In this case‚ an increase in temperature increases solubility. For some substances‚ heat is released when they dissolve in a given solvent. The reaction is called exothermic. In this case‚ an increase in temperature

phycobilins. There are several kinds of chlorophyll and they are greenish pigments. The most important one is chlorophyll A which is very important in making photosynthesis possible. Carotenoids are red‚ orange or yellow pigments and phycobilins are water soluble pigments found in the cytoplasm. (www.berkely.edu) Chromatography comes from the Greek words chroma and graph for Color Writing. The technique was developed by Mikhail Tsvet who used it for separating pigments that made up plant dyes. Chromatography

Yeast Lab Report Guidelines 1. Lab reports are to be computer-generated and double-spaced. All sections of the report must be written in paragraph form. 2. Do not use encyclopedias (Internet or otherwise)‚ dictionaries ((Internet or otherwise)‚ or personal web pages as sources for the report‚ this includes Wikipedia. You may use a textbook‚ lab manual‚ and/or article(s) in a published journal. You can find journal articles by going to the library website: http://www.lib.clemson.edu/ and selecting

Synthesis of Tetraphenylcylopentadienone Post-Lab Report Purpose- This experiment illustrates the use of adol condensation for the synthesis of a five-membered carbocylic ring. It is also a good demonstration of the impact extended conjugation has on the absorption of visible light. The reactants are bright yellow in color while the products are a very deep purple color appearing almost black. Introduction- The synthesis of Tetraphanylcyclopentadienone was a further example of the adol

corresponding test are as followed; Sudan IV is used for testing for lipids‚ if in fact a lipid is present‚ the reaction would produce a red/orange color as opposed to no change at all (negative reaction: Stays pink color). This solution of Sudan IV is soluble in lipids‚ but not in water. Benedict’s solution is the test used for reducing sugars or glucose testing. The positive reaction for this test should show a red/brick color after being placed in boiling water for three minutes‚ but if a negative
