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

Every step in this experiment has reasons behind its application. One determines the masses of the crucible and barium chloride hydrate for obvious data collection and calculation purposed. The heating of the sample slowly for 10 minutes is done to remove the water from the sample. A constant mass for the sample must be obtained so therefore it must be done slowly because if not you may loose mass from the sample. At the point where the crystalline solid changes to a powdery solid the sample must

ISE: The Determination of Chloride Unknown: #34 I. Purpose: In experiment V‚ “ISE: The Determination of Chloride”‚ the concentration of an Unknown Chloride solution‚ and the Wt% of NaCl in a sample of celery salt‚ were both determined. To determine the concentration of an Unknown Chloride solution‚ a Calibration plot is first prepared. The Calibration plot is made by first measuring a series of known concentrations of Cl- (with the same activity of the unknown solution) and obtaining
