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

Consequences of Medical Professionals Breaching the Code of Ethics CM107-60 Professor D. Barton February 08‚ 2013 Consequences of Medical Professionals Breaching the Code of Ethics The study and evolution of medical ethics has been around for centuries. (Cassidy‚ Barry‚ Blessing and Dennis 2008) stated that “In the 5th century BC‚ the Hippocratic Oath was considered to be the beginning‚ if not the foundation of a medical code of ethics”. Medical ethics are considered

or vary in some way. By employing both experimental and control groups in an experiment‚ investigators are enabled to rule out the possibility that something other than the experimental manipulation produced the results observed during the experiment. This type of research can be broadly divided into three main types: The Laboratory Experiment‚ The Field Experiment and The Natural Experiment. In a laboratory experiment‚ there is a systematic variation of the independent variables while other irrelevant

v. Reliability The experiment was unreliable. This is because no repeat trials were performed. A number of possible inconsistencies were outlined with regards to accuracy. As no repeat trials were performed‚ the results obtained may have merely been the outliers in the experiment so therefore be unreliable. This is because repeat trials need to be performed until a constant result is obtained in order for the experiment to be considered reliable. Ideally‚ a number of repeat trials should have been

less. Literature Review Many experiments have been conducted to test the strength and absorbency of paper towels. While the steps of the experiment vary from test to test‚ all of experiments are testing the same two factors; how much water can each paper towel brand absorb and how strong are each of the paper towels. Below I have reviewed the process and results from three experiments that are similar to the one I will be using. In the first experiment‚ the tester uses five brands of paper
