DETERMINATION OF COPPER BY COMPLEXATION‚ SOLVENT-EXTRACTION AND SPECTROPHOTOMETRY ABSTRACT To determine the concentration of copper in an unknown solution by using copper complexation‚ solvent extraction and spectrophotometry. Standards are used to create a calibration curve and the unknown concentration of copper is then calculated by using the linear equation from the calibration curve. The concentration of copper in the unknown solution 201 was found to be 12.57± 0.25 μg/mL. INTRODUCTION Copper

The determination in Animal farm and the journey they faced was compacted. Animal Farm by Gorge Orwell was a yet aggravating book. It caused many disconcerted emotions. This book is a very good example of the history of the Soviet Union. This book gives a very good understanding to young adults who read it. I realized the events that took place during that time were atrocious and so much people were suffering and in pain while the power that went to Stalin’s head was effecting so much people and

lab is to determine the identity of an unknown liquid by measuring its density and its boiling point and try to match it with those solutions given in Table 2 of experiment 2. Procedure Part A In Part A‚ The main purpose was to find the determination of the density of the unknown (j41) and by doing that we had to determine volumes of the unknown liquid (j41) using three different volumetric devices which are graduated cylinder‚ pipette and burette. Then we had to perform three measurement

In the poem "Ex-Basketball Player" the author John Updike asserts the theme that some people spend their entire lives remembering the past instead of focusing on their present future. The character in the poem‚ a man named Flick Webb use to be a very good basketball player in high school. He seems to be caught up in what he was and not what he is now. His life is just passing by him because he is stuck in the past and not focused on what he is doing in his life now. He floats around on his job and

Solubility Product Determination Purpose • To determine the solubility product constant‚ Ksp‚ of an ionic compound. Introduction The solubility product constant‚ Ksp‚ is a particular type of equilibrium constant. The equilibrium is formed when an ionic solid dissolves in water to form a saturated solution. The equilibrium exists between the aqueous ions and the undissolved solid. A saturated solution contains the maximum concentration of ions of the substance that can dissolve at

Complexometric Determination of Water Hardness Kayla Partridge Britni Gonzales 09/15/2014 Abstract Determining the water hardness of unknown sample #55 was determined by complexometric titration. With the use of disodium salt EDTA as the solution to chelate the metal impurities and the Eriochrome Black T indicator as the solution used to help visualize when the impurities were completely chelated‚ along with a few other solutions to help the reaction. Unknown water sample #55 experimental

Chemistry 121 Experiment 19 Molar Mass Determination y Depression of the Freezing Point Introduction: The most commonly used liquid is water. In this experiment we study the equilibria that can exist between pure water and an aqueous solution‚ and ice‚ the solid form of water. The heat will transfer from a higher temperature to a lower temperature. In order for water to change states of matter‚ it takes a certain amount of kinetic energy or heat. The shift from ice to water (solid to a liquid)
