Experiments 4A-C: Synthesis and Component Analysis of an Iron (III) Oxalate Complex My Name TA‚ Section B## Work Performed on 10/23‚ 10/30‚ & 11/4‚ 200# Report due Tuesday‚ November ##‚ 200# 1. Abstract This experiment initially involved the synthesis of an iron (III) oxalate complex with the general formula Kw[Fex(C2O4)y]·zH2O. The variables x‚ y‚ and z were determined through the duration of the entire experiment. From 1.2000g of Fe(NH4)2(SO4)2 were synthesized 1.1###g of K3[FeIII(C2O4)3]·3H2O

(0.104g of NaC2O4)(1 mol NaC2O4 /134.0g)(2 mol KMnO4 / 5 mol NaC2O4)(1/32.5 mL)(1000 mL /1L) = 0.00955 M KMnO4 2. Using the standardized concentration of KMnO4 calculated above to find the mass percentage of the oxalate ion Equation: Volume of KMnO4 reacted with Oxalate ion = (Vol of KMnO4 used in titration - Vol of KMnO4 used in blank titration) Titration Trial 1 Vf - Vi = VT 54.6 mL -28.1 mL = 26.5 mL 26.5 mL KMnO4 (1 L/ 1000 mL)(0.00955 M KMnO4 / 1L)( 5 mol C2O42-

Chapter 14 - Kinetics of a Particle : Work and Energy In this chapter‚ students will get to learn about the concepts of involving work and energy including the work of a force that acts on particles. Therefore‚ students can develop the principle of work and energy and the concepts of a conservative force as this equation can be useful for solving problems involving force‚ velocity and displacement and also can solve the kinetic problems. So in general‚ this chapter will enable students to analyse

Wrought Iron Fencing Is Ideal When You Want A Decorative Fence That Provides Home Security If appearance is important when choosing fencing material‚ then wrought iron might be a good choice for you. Wrought iron is one of the more expensive types of fencing‚ but it gives your property an upscale appearance. It complements any yard‚ even the property of a luxury estate. However‚ beauty isn’t the only reason to have a wrought iron fence installed. Here are some of the other advantages this type

calcium ions during contraction of a skeletal muscle? Calcium is an important element for live. Calcium is found in the bones of animals and humans. In muscle contraction is produce as a result of Calcium ions ‚ Ca2+‚ It comes from rapid release from the cisternae of the sarcoplasmic reticulum which cause a chemical reaction between ATP and the myofilaments. Another important function of Calcium ions occurs during the state of resting muscle. During the state of resting muscle‚ calcium Ion is “maintaining

Chemistry 1225 Lab Write-Up #13 Abstract Electrolysis is a method of using a direct electric current to drive an otherwise non-spontaneous chemical reaction. During electrolysis‚ hydrogen atoms (H2) are reduced at the cathode whereas the oxygen atoms (O2) are oxidized at the anode. There were three different solutions used in the experiment in order to have a better understanding of electrolysis reactions. From each solution‚ reaction equations were produced. The reactions could be observed from
