Spectrophotometric Determination of an Equilibrium Constant Introduction: In this experiment‚ you will study the reaction between aqueous iron (III) nitrate‚ Fe(NO3)3‚ and potassium thiocyanate‚ KSCN. They react to produce the blood-red complex [Fe(SCN)]2+. Fe3+ + SCN- ( [Fe(SCN)]2+ The equilibrium constant expression may be expressed as: K = [pic] You will prepare a series of standard solutions that contain known concentrations of [Fe(SCN)]2+ and will determine their absorbances

Those hard-to-pronounce chemicals that are in the list of ingredients on the label are used for more than just flavoring‚ appearance‚ and preserving the food (Food Additives). Those additives are used in some other very harsh items such as bug repellent (Food Additives). However‚ there are some simple and sustainable options that can help consumers avoid running into harsh chemicals and additives that may be lurking in their food. These changes will not

HARPER CHEMICAL COMPANY The Harper Chemical Company (HCC) was a medium sized producer of industrial chemicals‚ which sold its products primarily to customers in the paper industries and the paint industries. In 1980‚ HCC diversified into the production of a mineral called Dominite. By acquiring the Dominite activities‚ HCC hoped it would yield at least 15% return on investment after taxes. In early 1980‚ the HCC board of directors authorised the construction of a processing plant having a 40 000

Understanding Equilibrium in the IS/LM Model 1995 version Prof. Humberto Barreto1 Introduction: This brief work is designed to provide additional ammunition for the student in the ongoing war against IS/LM confusion and ignorance. The author has claimed in his Notes on Macroeconomic Theory (1995) that‚ There should be no mystery or uncertainty surrounding the IS/LM analysis at this point. IS/LM curves are simply a short-cut to finding the equilibrium values for income and interest rate. There
