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

In Stanley Milgram’s experiment‚ The Memory Project- effect on punishment on learning‚ the concept of staging in terms of what is real and not real in relation to the photographs objects and subjects‚ which is conveyed through the facilitator and the learner parallels Sontag’s concept of framing and representation In Plato’s Cave‚ and Barthes idea of posing and theater in Camera Lucida. Sontag and Barthes’s understandings of photography’s “reality” intersect in that their notion of the object in

How is the tissue of the kidneys structurally modified to aid in filtration? It has tubules and is porous B. What is important functionally about transitional epithelium? It allows for stretching. Transitional epithelium contains cells that are flattened and cells that are cuboidal; hence the name "transitional". You can find transitional epithelium in the bladder and in the first expansion of the ureters as they leave the kidneys (called a calyx). C. What is the function

The milgram experiment. The three people involved were: the one running the experiment‚ the subject of the experiment a volunteer‚ and a person pretending to be a volunteer. These three persons fill three distinct roles: the Experimenter an authoritative role‚ the Teacher a role intended to obey the orders of the Experimenter‚ and the Learner the recipient of stimulus from the Teacher. The subject and the actor both drew slips of paper to determine their roles‚ but unknown to the subject‚ both slips

Laboratory Techniques and Measurements Lab 1 The purpose of this lab was for the student to get involved with his or hers new lab kit as well as being able to know‚ identify and use each other tools provided in the kit. Another key learning aspect of this lab is to teach the student how to measure properly the many units in the SI system. I will be using laboratory dilutions‚ measurements‚ and weights to then calculate using algebraic formula. Throughout lab one we were introduced to

calcium carbonate. 0.00680 moles CaCO3 x 100 g CaCO3 1 mole CaCO3 = 0.68g CaCO3 Show the calculation of the percent yield. Actual yield/Theoretical yield x 100 (0.5/0.68) x 100 = 73.5% Conclusion: The objectives of this experiment are to predict the amount of product produced in a precipitation reaction using stoichiometry‚ to accurately measure the reactants and products of the reaction‚ to determine the actual yield vs. the theoretical yield and to calculate the percent
