The hypothesis of this experiment is that this plant pigment from spinach will contain the chlorophyll pigment or may contain the others too. Chlorophyll: Chlorophyll a is the main component of the plant pigments. This is used for the most important process‚ Photosynthesis. Chlorophyll a makes up about 75% of the plant pigment. The other 25% is the chlorophyll b. Figure 1: Chlorophyll a (http://brsmblog.com/wp-content/uploads/2011/12/0-chlorophyll-a-1024x735

There is undeniably a chemical side to addiction. If a person consumes a substance‚ it can have an effect on the brain (Clinton‚ 2009). Pharmacology is simply the study of how the body reacts to medicines and how those medicines affect the body (National Institute of Health [NIH]‚ 2011). Methods

Summary Purpose To purify the component (unknown) of Pancetin from last experiment and then compare its melt point to the two other possible substances. Theory Panacetin should be made up of about 50 percent of the unknown component that we previously separated out of Panacetin for testing. We suspect that this unknown compound is either acetanilide or phenacetin. From the solubility of acetaminophen and phenacetin‚ we could know both of them are relatively soluble in boiling water but insoluble

Laboratory #16: Analysis of Grease in Water by Solvent Extraction Experiment Date: 2/19/10 Due Date: 2/26/10 II. Objective The goal of this lab was to determine the amount of impurity‚ in the form of oil‚ in water using the method of solvent extraction‚ also known as liquid-liquid extraction‚ a method of separating two materials with different physical and/or chemical properties. Two methods of evaporation will be used to finally determine the concentration of impurity- one using an explosion-proof
