DISSOLVED OXYGEN BY WINKLER TITRATION 1. Background Knowledge of the dissolved oxygen (O2) concentration in seawater is often necessary in environmental and marine science. It may be used by physical oceanographers to study water masses in the ocean. It provides the marine biologist with a means of measuring primary production - particularly in laboratory cultures. For the marine chemist‚ it provides a measure of the redox potential of the water column. The concentration of dissolved oxygen can be readily

It is hypothesized that as the substrate concentration increases‚ the rate of reaction will increase respectively‚ until the enzyme reaches its optimum point of saturation‚ after which any increase in the substrate concentration will no longer affect the rate of reaction. The independent variable in this investigation is the varying concentrations of the substrate (Hydrogen Peroxide: 1%‚ 3%‚ 5% and 6%)The dependent variable was the rate of enzyme catalase activity‚ which was measured by the volume

carbon dioxide would be produced if 100 g of butane (C4H10) is completely oxidized to carbon dioxide and water? Theoretical Oxygen Demand (ThOD) • It is an environmental engineering application of stoichiometry. • The estimation of the amount of oxygen a known organic chemical will consume as it is converted to carbon dioxide and water. • It is simply the amount of oxygen required to convert the material to carbon

Specificity of Protein-Ligand Binding 1). One can conclude that Orange G. has the lowest affinity for the albumin. In the experiment the concentration of Orange G that binds to protein was a lot less than either Ponceau S. or Bromophenol blue. The ligand with the highest affinity to BSA was a little more difficult to decipher. The experiment shows that all of the 2 µL of both Ponceau S. and Bromophenol blue bind to the BSA. However‚ when 5 µL of the ligand is added the BSA is saturated and cannot
