solute within the membrane, the greater the rate of osmosis and change in color of the solute due to an increase of Lugol’s Iodine diffusing into the membrane and reacting with the starch. Ruba Nizam 3/18/2014 Introduction The purpose of this lab is to test the rates of osmosis on a model of a selectively permeable membrane filled with varying levels of starch concentrations using dialysis tubing. This experiment will make it possible to see how particles move from an area of high concentration

reaction did not happen, and the diphenylmethanol was not formed. This experiment was not successful mainly because no Grignard reagent or tiny amount of Grignard reagent was produced or active prior to addition of benzaldehyde. By the end of the lab, only berry-redish solution was produced without any solid, this is a physical evidence of not producing any diphenylmethanol, because diphenylmethanol is white crystal. Also, after adding bromobenzene, it was barely seen bubbling in the flask; however

Abstract In this lab we tested the contamination of water using oil, vinegar, and soap. Using plain tap water I added various amounts of contaminants to the water and noted the change. Introduction The introduction should describe the background of water quality and related issues using cited examples. You should include scholarly sources in this section to help explain why water quality research is important to society. When writing this section, make sure to cite all resources in

The purpose of this lab was to get used to using lab machinery such as the spectrometer. Spectroscopy is the interaction of matter and electromagnetic radiation. Most of our lab was based on the idea that matter would absorb and then reflect the colors we wanted to see based on the dyes we used. We also tested how strong the dyes were by testing them on filter paper and seeing how far they would travel up the paper. During dry lab we put all the classes’ data together to get accurate absorbance averages
