Total dissolved solids

Chemical Reactions I Purpose The purpose of this experiment was to test and see how four different chemical reaction worked. The four different chemical reactions are formation, decomposition, single-replacement, and double-replacement. The hypothesis of this experiment was that in each of the different reactions something would happen to the reactant whether it be color, mass, temperature, or pressure. II Equipment For this experiment Late Nite lab was used. In Late Nite Lab the equipment…

Application of Biofloc technology in aquaculture systems; a viewpoint Anjali P. Thilakan1*,Manju Lekshmi. N2.,Sreekanth.G.B2, N. P. Singh2 1Central Institute of Fisheries Education, Andheri (W), Mumbai 2ICAR Central Coastal Agricultural Research Institute, Ela, Old Goa . Abstract Bioflocs are aggregates (flocs) of algae, bacteria, proto¬zoans, and other kinds of particulate organic matter such as feces and uneaten feed and it normally contains 35-40% of protein. Biofloc technology ensures…

solutions of phosphate buffer of pH 6.8 were prepared as per USP25. Standard drug solution was prepared (1mg/ml) in Phosphate Buffer 6.8. The λmax was determined in respective solvent and found to be 272nm. Drug (100mg) was dissolved in10ml of Phosphate Buffer6.8 and the total volume was brought to 100 ml with Phosphate Buffer 6.8 to obtain stock solution .Stock solution was further diluted to obtain 5-30 μg/ml with Phosphate Buffer6.8. Standard solutions of Atorvastatin (10μg/ml) in Phosphate…

beans are then carefully heated so as to minimize protein damage. The oil is removed from flakes through the process of solvent extraction. In solvent extraction the flakes, or soy flour in some cases, are soaked in a solvent such as hexane. The dissolved oil combines with the solvent to form a miscella mixture which is removed through evaporation. After the solvent is mostly removed, through the process of desolventization, the soy flakes or flour contain little oil and a high concentration…

Humanity has an inherent drive for superior understanding of our Solar system and to find environment similar to that of planet Earth which could contain life. As consequence, there have been several space missions to analyse climate, assess data and search for geological evidences of life. With net expenditure of approximately three billion dollars, the Cassini-Huygens space mission to Saturn system was a joint assignment among finest space agencies; National Aeronautics and Space…

causing serious threats to environment and agro-ecosystem. This procedure can bring about a danger in the human wellbeing. The potential issues in environment brought on by pesticides, inorganic fertilizers, composts, agriculture residues, wastewater, solid waste, sewage, transgenic living beings. The outcomes are an increment in harmful components in air, soil and water…

Background This experiment was performed to determine the identity of an unknown organic liquid using physical constants: physical state, color, and odor, the solubility classification: water soluble or insoluble, the results of characterization tests: Lucas test, 2,4-Dinitrophenylhydrazine test, Bromine in Methylene Chloride test, and Ferric hydroxamate test, and analyses of spectral data: IR spectrum and HNMR . All testing samples were added to testing tubes for observation. Data was…

Manganese dioxide (MnO2) 2. If the temperature of a reaction is decreased, what effect will this have on the rate of reaction? A. It will have no effect. B. The reaction will stop. C. The rate of reaction will increase. D. The rate of reaction will decrease. 3. Given the equilibrium reaction in a closed…

2007). Whereas, the solubility, S, can be defined as the amount of gas dissolved into the polymer divided by the volume of sample for 1 atm of gas on the sample surface. (2.26) When, , , then the above equation can be rewritten as and when p1 = 1 atm (2.27) Where, c1 is the concentration in the sample when the equilibrium is reached. The solubility S is expressed in cm3 of gas at STP per cm3 of the solid at a pressure of 1 atm. (cm3 STP/cm3 atm). Equation (permeability)…

The Indian subcontinent has served as a major corridor for the genetic diversity of its inhabitants. Modern-day human population dispersal routes is punctuated with delineating migrations that eventually led anatomically modern humans (AMH) to spread over most parts of the world within the past 100,000 years (Cavalli- Sforza, Menozzi and Piazza 1994; Lahr and Foley 1994). Migration waves are influenced by landscape traversed and thus, natural inter continental passageways acting as corridors…
