Ashley Silva Lab 7: Three Stooges in Chemical Reactions Objective: The purpose of this lab is to experimentally determine the equilibrium constant‚ Kc ‚ for the following chemical reaction: Fe3+ (aq) + SCN-(aq) ↔FeSCN2+(aq) Background Information: A system is at equilibrium when the rate of the forward reaction is the same as the rate of the reverse reaction. There is no change in concentration for the reactants or products at chemical equilibrium. When the system is disturbed there is

LE CHATELIER’S PRINCIPLE Castro‚ Lharize C. Experiment # 1 I. Introduction: In this experiment‚ using Le Chatelier’s principle‚ we will observe several responses of a system at equilibrium to various changes in external conditions. The experiment aims to investigate two equilibrium systems: (a) cobalt complexes and (b) chromate-dichromate equilibrium and explain observations in light of the Le Chatelier’s principle. II. Theory/Concepts: In 1884 the French chemist and engineer Henry-Louis

07.05 Le Chatelier ’s Principle Research Project Fritz Haber was born in December of 1868‚ in Prussia to a German chemical merchant. He went into the field of organic chemistry at the University of Jena. He was appointed as director of the Kaiser Wilhelm Institute for Physical Chemistry in Berlin in 1911. He was in charge of forming a center for cross-disciplinary research and gave his country the knowledge of ammonia and other significant fertilizers. He left Germany in 1933 after their loss

ENDING!” Seeing this‚ what would be a topic to ruminate about at that moment? Is the world really ending? Is this just propaganda like so many other things? I agree with the quote “The desk is a dangerous place from which to watch the world” by John Le Carre because it relates to what people think and how their outcome can change the situation. This in fact is the situation in most cases since it relates to so many exemplary actions. Relating it back to the example‚ one wouldn’t believe that the

Chemistry 12 Santa Monica College Determination of Kc for a Complex Ion Formation Objectives • • Find the value of the equilibrium constant for formation of FeSCN2+ by using the visible light absorption of the complex ion. Confirm the stoichiometry of the reaction. Background In the study of chemical reactions‚ chemistry students first study reactions that go to completion. Inherent in these familiar problems—such as calculation of theoretical yield‚ limiting reactant‚ and percent yield—is

Determining the Ksp of Calcium Hydroxide by Titration of Saturated Ca(OH)2(aq) with HCl(aq) Abstract: Titration is a technique that has been used in this experiment to identify the Ksp value of calcium hydroxide in order to determine the extent to which the compound is soluble in water. A known volume of 50 mL of hydrochloric acid‚ a concentration of 0.05 M hydrochloric acid‚ a volume of 50 mL calcium hydroxide base‚ an unknown concentration

Restoring Balance LeChâtelier’s Principle and Equilibrium Introduction Chemical equilibrium is a true balancing act. What happens when the balance is disturbed? The purpose of this lab is to observe the effects of concentration and temperature on equilibrium and to visualize how balance can be restored based on LeChâtelier’s Principle. Background Not all chemical reactions proceed to completion‚ that is‚ to give 100% yield of products. In fact‚ most chemical reactions are reversible. In
