EXPERIMENT 5 REDOX TITRATION: TITRATION USING SODIUM THIOSULPHATE Objectives 1. 2. To prepare a standard solution of potassium iodate for use to determine the concentration of sodium thiosulphate solution accurately. To acquire the proper techniques of carrying out a titration. Introduction Redox titrations using sodium thiosulphate as a reducing agent is known as iodometric titration since it is used specifically to titrate iodine. The reaction involved is: I2 + 2Na2S2O3 I2 + 2S2O322NaI + Na2S4O6

Experiment : 1 Tittle : Preparation of bis(acetylacetonato)copper(II) complex Objective : To synthesis the bis(acetylacetonato)copper(II) complex Introduction : A complex ion is usually form with high charge density metal ion as a central and formation of coordinate covalent bond (dative bond) with high electron molecules or ions. These molecules or ions are functioning as ligands (electrophile in organic compounds). They are easily attracted by electrophile (electron deficiency

Determination of Water Hardness Using a Titrator Heather Crall Chemistry 1 SMT- 271044 10/17/2012 Abstract From seeing all of my results and conclusion I now see that I didn’t understand this lab very well and that its not easy when others try to help. Since I have hard water it tells me that my water flows over and through rocks and minerals‚ like limestone. Purpose The purpose of this lab is to become familiar with the concept of water hardness. We learn that hard water contains

Bending Moment EXPERIMENT 2B: SHEAR FORCE AND BENDING MOMENT 1. ABSTRACT Performance-based design approach‚ demands a thorough understanding of axial forces. Bending characterizes the behavior of a slender structural element subjected to an external load applied perpendicularly to a longitudinal axis of the element. By this experiment we can verify the limit load for the beam of rectangular cross-section under pure bending. Moments at the specific points are calculated by the method of statics

There are three basic types of bridges‚ two of them are the arch and beam bridge. Of the first type the form of the load-bearing structure or its actual shape is convex. The load of an arch bridge is carried outward along the curve of the arch to the abutments at each ends. These abutments or supports carry the load and keeps the ends of the bridge from spreading out. Arch bridges can be divided into two major types‚ the old and the modern arch bridges. Under the first types are the Corbel arch

1 2 CHAPTER Distribution Customer Service and Logistics If you want a Coca-Cola‚ there’s usually one close by— no matter where you might be in the world. And that’s no accident. An executive for the best-known brand name in the world stated the objective simply: “Make Coca-Cola available within an arm’s reach of desire.” To achieve that objective‚ Coke works with many different channels of distribution. But that’s just the start. Think about what it takes for a bottle‚ can‚ or cup

Kaplan University CJ340: Applied CJ Ethics Unit 4 Assignment August 26‚ 2013 Merriam-Webster’s dictionary defines “slippery slope” as a course of action that seems to lead inevitably to from one action or result to another unintended consequence (Merriem-Webster‚ 2013). The “slippery slope” can refer to almost every walk of live but here it is being applied to law enforcement and accepting gratuities. Here it is referring to police officers accepting what may seem to be harmless

Continuously variable slope delta Modulator INTRODUCTION:- Continuously variable slope delta modulation (CVSD or CVSDM) is a voice coding method. It is a delta modulation with variable step size (i.e. special case of adaptive delta modulation)‚ first proposed by Greefkes and Riemens in 1970. CVSD encodes at 1 bit per sample‚ so that audio sampled at 16kHz is encoded at 16kbit/s. The encoder maintains a reference
