Solid Mixture by Liquid-Liquid Extraction Introduction Liquid-liquid extraction is a technique used to separate chemical substances in order to purify or identify the various components of a mixture. Flavors‚ spices‚ perfumes‚ and medicines are just some of the everyday things that are extracted from plants and other natural sources [1]. The basic principle used to carry out this separation is the mixing of two liquids that are immiscible with each other. This creates layers of liquid‚ which can be

This experiment was performed to demonstrate a cycle of chemical reactions involving copper. This lab will start with copper as a reactant in the first reaction through a series of five chemical forms of aqueous phase reactions and ending to calculate the percentage of recovered solid copper as a product in the last reaction of the experiment. The experiment resulted in a percent recovery from the cycle of copper reactions of an increase to 139%. . Introduction: The purpose of this experiment is

a reaction. Moreover‚ it also tells you how a particular mixture of chemicals will react. This is because chemical reactions always occur in the direction which will make the ratio of their products to reactants equal to the equilibrium constant. In chemistry‚ Le Chatelier’s principle‚ also called Chatelier’s principle or "The Equilibrium Law"‚ can be used to predict the effect of a change in conditions on a chemical equilibrium. The principle is named after Henry Louis Le Chatelier and sometimes

I. Introduction There are two types of chemical reaction that occur one goes only in one direction and the other one is reversible. A reversible reaction is when a products starts to form the backward reaction starts where the products turns back to reactant molecules. When the rate of forward and backward reaction is already equal and the concentrations of the reactants and products no longer change with time we can say that chemical equilibrium is already achieved. A reaction is said to be at

Q_1 From the Exhibit 4‚ U.S. Frasch Sulphur Industry Prices and Profitability‚ 1940-1967‚ we can get the information about the variations in the return on invested capital earned by the industry over the several decades. In sulphur industry‚ the return on invested capital was around 15% from 1940 to 1945. From 1946‚ rate of return began to increase dramatically‚ starting from 16.2 %( 1945)‚ and reached 33.8% in 1950. This high rate of return kept for couples of years (1951-1955)‚ ranging from 29%
