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

someone tells them to. 2. What were Milgram and Zimbardo’s findings? In Milgram’s initial obedience experiments he found all of the participants administered shocks to the confederate up to the 300-volts while 26 of the initial 40 participants administered fatal electric shocks. When he repeated the experiment he found nearly 70% of participants would administer a fatal shock if instructed by an authority figure to do so. In the Stanford Prison Experiment‚ Zimbardo found both the student guards

In conclusion‚ after conducting the lab‚ the emergent properties of water were tested and proved. These trials and experiments were able to verify the adhesion‚ cohesion‚ polarity‚ temperature stabilization‚ solvency‚ and density changes exhibited by water. During the glass and wax paper lab‚ we observed the adhesive properties of water. When a droplet of water touched the glass‚ it dispersed immediately. The droplet placed on the wax paper remained intact and in droplet form. Also‚ when the

Lab Conclusion on Density In the lab of measuring density‚ precision and accuracy are very key components. Precision is the exactness of a measurement or good technique. Now accuracy is the value that we measured compared to the true value that the book has. Precision and accuracy are important because you need to have good technique and have your value close to the true value to minimize the error analysis. If you do these steps correctly you are a good chemist but if you do them poorly they

VI- CONCLUSION The eye is the organ of vision. It has a complex structure consisting of a transparent lens that focuses light on the retina. The retina is covered with two basic types of light-sensitive cells-rods and cones. The cone cells are sensitive to color and are located in the part of the retina called the fovea‚ where the light is focused by the lens. The rod cells are not sensitive to color‚ but have greater sensitivity to light than the cone cells. These cells are located around the

The essay starts off with Milgram explaining the history of obedience by exhibiting the loyalness that was portrayed by followers in historical documents. The experiment that Milgram set up was simple. He elected an “experimenter” who is the

Since a syllogism is valid if and only if the premisses entail the conclusion‚ diagramming the premisses will reveal the logical geography of the conclusion in a valid syllogism. If the syllogism is invalid‚ then diagramming the premisses is insufficient to show the conclusion must follow. | | D. Since we have three classes‚ we expect to have three overlapping circles. | 1.
