Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different

EXPERIMENT 5 REDOX TITRATION: TITRATION USING SODIUM THIOSULPHATE Objectives 1. 2. To prepare a standard solution of potassium iodate for use to determine the concentration of sodium thiosulphate solution accurately. To acquire the proper techniques of carrying out a titration. Introduction Redox titrations using sodium thiosulphate as a reducing agent is known as iodometric titration since it is used specifically to titrate iodine. The reaction involved is: I2 + 2Na2S2O3 I2 + 2S2O322NaI + Na2S4O6

This Changes Everything is a book that was created to disprove what people have chosen to believe in regards to climate change and their involvement in it. Naomi Klein forces people to remember climate change and disallow from being swept under the rug by climate change deniers. In this book‚ Klein attempts to accomplish the nearly impossible task of making everyone reflect on how much harm they have done to the environment. She debunks arguments against climate change in an attempt to get people

Correlation between the chemical activity of Amylase and change in temperature ABSTRACT This experiment focuses on how the change of temperature affects the rate of reaction of amylase. In the experiment there were four different environments that each contained 2 test tubes. Each test tube consisted of the same concentration and amount of starch and amylase. After having each test tube placed in these environments for several minutes a droplets of each mixture was placed onto each slot which

DIFFDiffusion of Chemicals * Diffusion-is the process whereby particles of liquids‚ gases‚ or solids intermingle as the result of their spontaneous movement caused by thermal agitation and in dissolved substances move from a region of higher to one of lower concentration. The rate of diffusion depends on the size of the surface area to the volume in the cell. The higher the surface area of cells in relation to their volume‚ the quicker diffusion takes place. Experiment on Diffusion Aim: to

Tricking children into behaving well in order to receive presents. Isn’t that bribery? Parents say that you should never lie and always tell the truth‚ but the way I see it is‚ they have gone against their word and become a hypocrite.
