Seaweed Lab – Summary Our focus questions for this lab are the following, How can I make a pharmaceutical product from seaweed and can a single substance be isolated from a mixture, what is this substance? The chemicals used in this experiment to help us answer these questions are: Iodine crystals, tincture of iodine from a pharmacy and Laminaria or seaweed. The objective is to make a tincture of iodine. Iodide will be added to iodine, and a Bunsen burner will be used to heat and filter the solution. The seaweed will be cut and weighed (6 grams) and transferred into 150 mL solution.

Do not go into detail about the protocol. The purpose of the experiment was to determine the optimal pH and temperature of a phosphatase enzyme found in a crude protein extract isolated from alfalfa sprouts. The temperature optimum was found to be 55°C, and the pH optimum was found to be 5. Thus, the phosphatase enzyme can be classified as an acid phosphatase. 5.

Experiment 11 Lab Assignment Answer Sheet: Chromatography of Food Dyes Name: Pre-Lab: Define the Rf value of a compound The "rf" value is the distance the compound moves relative to the distance the solvent moves. Data and Observations: Record the distance travelled by the sample and the solvent in the table below and calculate the Rf values. Table 1.

In June of 2000 the cap requirements were changed from a multi-media cap to a geosynthetic clay cap. OU2’s elements were ground water removal via on-site extraction wells, ground water treatment (air stripping) for removal of VOC’s, discharge to a local water treatment plant and continued monitoring. In 2005 an amended report eliminated the removal and treatment part and, instead, replaced it with an injection of vegetable oil as a bioremediation of the VOC’s with monitoring. OU’3 excavation and stabilization of contaminated soils, on-site disposal of the stabilized soil, installation of a low permeability cap over the treated soil, placement of one foot of topsoil over the remainder of the uncapped site and placement of controls. The clean up approach for OU4 was to allow the clean up of the other operable units to address the contamination of the wetlands.
