to increase in direct translation to the concentration increasing. The theory surrounding this lab was to see in practice how density could be determined with displacement and then to determine whether the density does in fact increase directly with the concentration.

and just basic starch). We tested each of these with our three unknowns (which were the three separate protein supplements). Mixing each individual supplements with all of our reagents and stock solutions‚ we tried to obtain a positive or negative reaction to decipher if the supplement was indeed protein positive. We also tested each supplement with a constant volume of H2O to have a standardized measurement to compare our data back to. In every mixture there was 5 ml of (stock solution/the three unknowns/our

The procedure was taken from “From Drosophila cDNA in E. coli plasmid to homologous human proteins” lab manual (4). - Colony Picking: Two E. coli colonies were grown on agar plates and treated with ampicillin. They contained the plasmid with genes for ampicillin resistance and Drosophila cDNA sequence. - Plasmid Isolation: We used the QuickLyse Miniprep Plasmid DNA purification systems to isolate the plasmid DNA. Indeed‚ the bacterial cells were removed from the liquid broth and were resuspended

The purpose of this lab was to find out the reaction of iron nails and CuSO4‚ copper sulfate solution. Before starting the experiment‚ there were two possible outcomes of the reactions. CuSO4 + Fe → FeSO4 + Cu or 3CuSo4 + 2Fe → Fe2(SO4)3 + 3Cu. The ion chart showed that iron can only make two charges‚ +2 and +3. As the liquid evaporated‚ the weight changed because the liquid added to the nail’s weight. In a real world situation‚ scientists can use ratios to determine how much of a substance that

Constant of an Unknown Ester Hydrolysis Reaction Abstract The experiments to follow determined that the equilibrium concentrations of the reaction: ester + water ↔ alcohol + acid‚ are equal to 0.0363 moles of ester‚ 0.2852 moles of water‚ and 0.0268 moles each of alcohol and acid. Using this information the equilibrium constant was determined to be 0.06938. 1. Introduction In this lab the equilibrium constant‚ Kc‚ for the acid catalyzed reaction between an unknown ester and water
