Experiment 18 Chemistry 101 Redox Titration: Determination of the Percentage of Iron in a Sample INTRODUCTION The concentrations of redox-active species can be determined by redox titrations. In a redox titration‚ a measured sample of the unknown is titrated against a standard solution of a substance that will oxidize or reduce the unknown. In the present experiment you will take a sample containing iron‚ add acid to dissolve it [thereby converting all the iron to iron(II)]‚ then

Batch Reactor Aim/Objective The aim of this experiment is to compare the theoretical conversion for a saponification reaction to the experimentally determined conversion in a batch reactor under constant temperature conditions. Experimental Procedure The first step was to ensure the electrical supply to the rig was turned off and that the Armfield batch reactor was empty and clean. 500mL of 0.1M sodium hydroxide solution was then added manually. The pump and stirrer were then set to

Determination of Chemical Formulae: The Reaction of Zinc and Iodine By Sarah Abstract: The main objective of this experiment was to use to the reaction between zinc and iodine to examine the validity of the Law of Conservation of Mass and the Law of Constant Composition. The Law of Constant Composition was tested by determining the mass of each of the reactants‚ zinc and iodine‚ and comparing their total to the mass of the zinc iodide product plus the excess zinc. The total mass of the reactants

The Sequence of Chemical Reactions Drew Selfridge Dave Allen‚ Lab partner Instructor Yang February 11‚ 1997 INTRODUCTION This experiment was to recover the most amount of copper after it is subjected to a sequence of reactions. The copper is originally in solid form‚ but the reactions will turn it into free Cu+2 ions floating in solution. The ions will then be regrouped to form solid copper once again. During this process‚ however‚ some of the Cu+2 ions may be lost. The copper will subjected

Determination of Cleansing Action of Detergents (Using Capillary rise) Synopsis This project report explains about the surface tension and capillarity of liquid through a simple experiment of finding the capillarity of various detergents. Oil stains and grease on dirty clothes cannot be removed‚ using water alone‚ because water does not wet them. If detergents added ‚ surface tension is decreased‚ the area of contact is increased

Do all liquids evaporate? What would happen if liquids never evaporated? Do we know which liquid evaporates the fastest? Could we perhaps use this knowledge to change the everyday processes? The process of evaporation happens much differently than scientists once thought. Every liquid eventually evaporates and often what remains is the solid particles which were once part of the solution. Evaporation is very important: “it shapes the climate of the planet‚ it affects the cost of car travel

High Performance Liquid Chromatography (HPLC) Instructor: Dr. Hüseyin BOZKURT High Performance Liquid Chromatography (HPLC) is one mode of chromatography‚ the most widely used analytical technique. Chromatographic processes can be defined as separation techniques involving mass-transfer between stationary and mobile phases. Present day liquid chromatography that generally utilizes very small packing particles and a relatively high pressure is referred to as high performance liquid chromatography

FE 106 GENERAL CHEMISTRY EXPERIMENT-1 DENSITY OF LIQUIDS PREPARED BY BURAK COBAN PURPOSE: In this experiment we will learn how can we find the density of liquids and liquids of density how change effect of temperature‚ pressure‚ mass‚ volume and concentration. For this reason we will take NaCI solutions with different concentrations and we will measure their densities‚ so we will find out the effects of concentration on density of solutions. THEORY:

UV2493 Version 1.5 DIAMOND CHEMICALS PLC (A): THE MERSEYSIDE PROJECT Late one afternoon in January 2001‚ Frank Greystock told Lucy Morris‚ “No one seems satisfied with the analysis so far‚ but the suggested changes could kill the project. If solid projects like this can’t swim past the corporate piranhas‚ the company will never modernize.” Morris was plant manager of Diamond Chemicals’ Merseyside Works in Liverpool‚ England. Her controller‚ Frank Greystock‚ was discussing a capital project that
