Acid dissociation constant

Discussion: Based off the results from this lab the student was able to determine whether the model cell and cell environment each represent a hypertonic, hypotonic or isotonic solution. The first solution cell and environment the student had, was water and sodium chloride. In this instance water was the model cell (what was in the dialysis tubing) and Sodium chloride was the surround environment (plastic cup). The initial weight of the model cell was 13.2g, but after sitting in the sodium…

hetero-pairs in BLOCK (Plot A) follows similar pattern as Shannon Entropy Method (Plot C). Second, diversity profile for substitution by a given residue follows a characteristic pattern (plot B and D). Positional diversity changes when BLOCK undergoes amino acid substitutions. It is maximum when a position in BLOCK, has maximum and fixed occurrence of a residue (here V, first residue) followed by multiple copies of a second one (here I, second residue) with or without others. When other residues…

Jessica Grandier Bio 204 section 201 Case Study 1a What are the normal values for PH, Erythrocyte count, Leucocyte count, Platelet count. ( 1 point each) The normal values for PH are 7.35-7.45, the normal erythrocyte count for males is 4.7 - 6.1*10^6 /ul million and for women it is 4.2 -5.4*10^6/ ul million, Leucocyte count is 4,800-10,00 mmm^3 of blood and normal platelet count is 150,00-450,00 platelet for microliters. 1b What are the terms used for increase and decrease in PH…

Effect of Organic Solvents on Particle Size When anti solvent was 0.4% (w/v) F68 aqueous solution, the effect of various good solvent was investigated. These organic solvents include ethanol, methanol, PEG 400, propylene glycol. The result as mention in Table 16 & Figure 27 showed that the particles prepared by methanol were the smallest (317 nm) among other organic solvents. Ethanol, PEG 400, and propylene glycol produced the particles having the mean particle size of 525nm, 1274nm, 864nm,…

Introduction The ferric chloride test is used to determine the presence of phenols in a given sample or compound (for instance natural phenols in a plant extract). Enols, hydroxamic acids, oximes, and sulfinic acids give positive results as well. The ferric chloride test can be used to detect metabolites in urine in case of inborn error of metabolism such as phenylketonuria. In addition,the Ferric Chloride test can be used to detect salicylates in urine after an aspirin overdose.1 Background…

Batch adsorption experiments Adsorption of the Pb2+ ions by the Fe3O4@GMA-AAm nanocomposite was measured from batch adsorption experiments by mixing 10 mg of adsorbent with an aqueous solution containing a predetermined concentration of Pb2+ ions (50 mL). The mixture was shaken at 200 rpm to reach equilibrium. After a specified time, the solid and liquid were separated by external magnet and the concentrations of Pb2+ ions were measured by AAS. To find the optimized pH in adsorption of Pb2+ ions…

Acid Mine Drainage (AMD) and Control Options AMD comes from the oxidation of sulphide minerals. It has the negative impact on the environment. Since it could affect the surface water, ground water quality and land used. This condition due to the low pH contains by the water (could reach up to 2), sulphate content (SO4), and metals content (Fe, Zn, Cu, Ni, As, Cd). The principles for AMD formation should be understood to be able to manage the water. i. Waste containing reactive sulphide (S2-,…

g/100g DW). The total and available carbohydrate were (36.82 ± 0.180 and 5.190 ± 0.212g/100g DW) respectively. The gross energy (GE) value of commercial dried laver was found to be (8467.69 ± 51.54 kJ.kg -1) as presented in Table 1. Amino acid analysis The amino acid composition…

WHAT IS FORMALIN? Formalin is the trade name for an organic compound made by formaldehyde and water. It has the chemical formula CH2O and its chemical structure is as shown in figure.1. Uses: Formaldehyde is used mainly in the production of plastics (such as urea-formaldehyde plastics which is used in many manufacturing processes due to its useful properties such as flexural modulus, and a high heat distortion temperature, high surface hardness, low water absorption, high tensile strength, mold…

the other three liquids. It was expected that whichever combination of liquid and black solid formed a blue solution would be H2SO4 and CuO hence, CuSO4 in solution. On identification of sulphuric acid, the following tests were performed expecting the evolution of carbon dioxide on reaction of the acid with carbonates. Therefore, among the soluble solids, (10) exhibited effervescence and was suspected to be sodium carbonate due to its solubility. The powders and crystals were divided…
