Objective: To determine the concentration and equilibrium constant for a reaction of colored product using absorption spectroscopy‚ to create a calibration curve for determining equilibrium concentrations by applying Beer’s law and to force the completion of a reaction by applying Le Châtelier’s principle. Procedure: A diluted solution was made from the stock of 0.0025 M Fe(NO3)3 by diluting 4.0 mL to exactly 100.00 mL‚ using serological pipet and volumetric flask. The concentration of the diluted

The Determination of Keq for FeSCN2+ Joy Muthami February 12 2014 Introduction: The purpose of this lab was to calculate the equilibrium constant for the reaction of iron (III) ions with thiocyanate ions. The materials were first acquired then with the groups in the class each team was given a test solution to create and acquire information from then all the information was put together in order to save time. Specifically the group created test solutions #8‚ #9‚ and #10. Once the solutions were

INTRODUCTION The solubility product constant‚ Ksp‚ is the equilibrium constant for a solid substance dissolving in an aqueous solution. It represents the level at which a solute dissolves in solution. A more a substance dissolves‚ the higher the Ksp value it has. In this experiment‚ a system of a sparingly soluble

be that more concentration of amylase speeds up the reaction time. Introduction The enzyme‚ amylase is found in the saliva of most animals and in humans. Amylase hydrolyzes starch‚ a plant’s reservation of carbohydrates. Amylase causes a chemical reaction in the polysaccharide starch that breaks down the glucose molecules into maltose. When diluted with a solution of I2KI‚ starch will change to a dark purple while doing the same to maltose‚ there would be no color change. The question posed
