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

The object of this particular experiment is to gain knowledge on diffusion across a plasma membrane‚ which is selectively permeable. Diffusion is the movement of a substance from a region of high concentration to lower concentration. Experiment 2 was performed to see how the substance’s‚ starch‚ and diffusion process across a plasma membrane is affected by amylase. We prepared a simulated digestive tract of a caterpillar‚ as the plasma membrane‚ to see if the amylase breaking down the cooked starch

Critical appraisal guidelines: Quantitative study Medication errors has always been a major problem in healthcare. Drugs errors continue to claim many innocent lives. The purpose of the research was to identified the causes of medication errors during cardiopulmonary arrest. According by the article by Flannery & Parli (2016)‚ medication errors in the intensive care unit (ICU) range from 8.1 to 2344 per 1000 patient-days. Unfortunately‚ drug errors that occurred during Cardiac resuscitation are less identified

Title: Osmosis and water potential Aim of the experiment: Finding the water potential of potato. Biological principles: Independent variable: concentration of the solution. Dependent variable: percentage changed in weight of the potato strips. Controlled variable: size of the potato strips‚ it can be controlled by cutting the length of the strips. Procedure: Table 1. Concentration of sucrose solution table Concentration/ M | Sucrose Solution/ ml | Distilled

however‚ sometimes we actually remember a misrepresentation of what’s really occurred. This is known as the misinformation effect‚ where misleading information distorts our memory of the true event. Important in a variety of aspects‚ these memory errors become especially crucial in terms of courtrooms and eyewitness testimony. Interestingly‚ 75% of false convictions are due to an eyewitness identifying the wrong person or misreporting how an event actually occurred. Witnesses aren’t intentionally

Fundamental Attribution Error (FAE) (Jones and Harris study 1967) The Fundamental Attribution Error (FAE) principle states that man tends to ignore outside pressure and factors when judging the behavior of others. This means that people believe that a certain action or behavior was a cause of an internal motive rather than some influence from external pressure. In simple words‚ the FAE describes the inability to step inside other people’s shoes. The name FAE was first coined by Ross in 1977

XBLR Error Study Keisha McDonnough Florida Atlantic University ACG 4401 Instructor Renee de Roche June 7‚ 2012 Extensible Business Reporting Language (XBRL) is a standards- based language that facilitates the interchange of interactive financial information via electronic communication.(FFIEC‚ 2006). The idea behind XBRL is straightforward- a digitized version of the text of the financial statement. XBRL treats specific identifiable information in a financial statement as an individual

Medical Errors Medical errors are avoidable negative effects of care‚ which can be harmful to a patient. These errors can vary from giving the wrong treatment to a disease‚ injury‚ syndrome‚ behavior‚ or infection a patient might have. Nurses play one of the most important roles in the avoidance of occurring medical errors. By doing their job correctly they can prevent the errors from happening and potentially hurting or killing a patient. Decimal errors‚ trailing zero errors and abbreviation errors

The Effect of Starch on the Activity of Amylase with pH Variable Lab Report‚ Fall 2011 East Tennessee State University Department of Biological Sciences By: Shelby Brackett Date Performed: October 10‚ 2011 Lab Instructor: Joseph Kusi Biology 1111‚ Section 018 Abstract Enzymes are very important in chemical reactions. They are used to speed up the reaction taking place. They act by binding to a specific substrate and form an enzyme-substrate complex that may put stress on chemical bonds
