Applications of Le Châtelier’s Principle (September 11 - 15‚ 2014) **The purpose of this experiment was to visually observe the effects of how changing certain aspects of the reaction affected the observed equilibrium. PROCEDURE: Introductory activity Part A: Effect of Concentration: Two different temperature water baths were created‚ one at 65-70oC‚ the other ice‚ and set aside for Part B. 20 mL of potassium thiocyanate solution were poured into a petri dish. The initial color and all subsequent

Le Châtelier’s principle states that The system will have one reaction dominate until the offsetting changes allow the rates of the forward and reverse reactions to be equal again (reestablishing equilibrium). If the forward reaction dominates in order to offset the changes‚ we say the system “shifts to the right” or “shifts toward products” in order to reestablish equilibrium conditions. This will increase the concentration of the products and decrease the concentration of the reactants. However

Chemical Equilibrium: Le Châtelier’s Principle Abstract This experiment entitled "Chemical Equilibrium" aims to help students to investigate the effects of concentration and temperature upon the position of equilibrium in a cobalt chloride solution‚ Co(H2O)62+. In this experiment‚ cobalt crystal is dissolved with distilled water and ethanol which the initial colour is purple-pinkish and a few drops of concentration of HCl is added to the test tube‚ the final colour is in deep blue colour.

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

his only successful product. His newest undertaking has been the classic musical‚ Les Miserables‚ which won several Oscars. Yet‚ this jaw dropping production earned mixed reviews from various critics. While critics all agree on Les Miserables plot and unsuccessful camera techniques‚ they differ on director Tom Hooper’s adaptation of the famous Broadway musical to the movie theatre and the actors live singing. Les Miserables’ plot is based on the novel written by Victor Hugo‚ set in 19th-century

CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive

Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and
