Introduction: Titration is a common laboratory practices that is involved in quantitative chemical analysis. This process is also called titrimetry or volumetric analysis (since we are dealing with volumes in our analysis). This process is used is used to determine unknown concentration of a solution. This is unknown solution is known as the analyte. The standard solution or known concentrations is called titrant. The titrant and analyte react to determine an accurate concentration of the unknown solution. This is the process that happens in titration. There are many types of titrations like acid-base titrations, redox titration, and gas phase titration, but the most commonly used titration is acid base titration. An acid base titration is used when an acid or base concentration needs to be known (for example this lab is an acid base titration). In the process of acid- ...

... For example, when weighing out the amount of HCL and NaOH needed for the standard solutions, the last decimal point on the mass number on the scale would be shifting. So this causes an uncertainty. This is another type error caused by instruments. The pipets for example wouldn’t be able to take in the right amount of solution because the edge is chipped or cracked. Also, if one did not calibrate the pH meter by Scholar 425. The value they receive would be an error. Also dirty burets that have impurities with chemicals or water would affect the concentration of solution. If this happens the molarity will be wrong and the volume would have been read wrongly. Overshooting the endpoint is another error this will give a steep rising curve and a drastic change in the pH. To deal with the change in pH more titrant will be used and thus affecting the volume and molarity.

- In 1971 three psychologists, Craig Banks, Curtis Haney, and Phillip Zimbardo were captivated in finding out whether the rough treatment described among guards in American prisons was due to the aggressive behaviors of the guards or the prisoners lack of respect for law and order (dispositional hypothesis) or had more to do with the prison atmosphere (situational hypothesis) (Maxfield & Babbie, 2009). If the prisoners and guards acted in a non-violent way this would corroborate the dispositional hypothesis, or if the prisoners and guards act the same way as people do in real prisons this would authenticate the situational explanation (McLeod, 2016)....

- Would you go into prison to get paid. Do you believe that you will come out the same or become different. Do not answer that. The Stanford Prison Experiment was an experiment that was conduct in 1971 by a team of researchers led by psychology professor Philip Zimbardo. Seventy applicants answered the ad and were narrowed down to 24 college students, which half were assigned either to be guards or prisoners by random selection. Those 24 college students were picked out from the of 70 applicants by taking personality tests and given diagnostic interviews to remove any candidates with psychological problems, medical disabilities, or a history of crime or drug abuse....

- The name of the experiment was the Stanford Prison Experiment, a study that was supposed to be for two weeks, lasting only six days. This study was conducted by Philip Zimbardo, a psychologist that taught at the university. Professor Zimbardo wanted to examine how volunteers would react in a simulated prison. Zimbardo and his colleagues put an advertisement in the local paper asking for participants. Then on Sunday, August 17, 1971 twenty-four applicants were placed in a mock prison, set up in the basement of the Stanford psychology building....

- 1. In Stanley Milgram’s original experiment where he studied the potential of a person to physically harm another when told to do so by an authority figure, he assigned three roles: experimenter, teacher, and learner. The experimenter and learner were complicit in the experiment’s intended goal to measure the threshold at which a person would disobey a command to administer increasing levels of shock treatment. The shock treatment was presented to the teacher as having 15 level increments ranging from 15-450 volts, with descriptions from “slight shock” to “danger: severe shock.” The experiment was disguised as an attempt to study the effects of punishment on memorization of word groups, and...

- Do you think Milgram experiment was ethical. Why or why not. You may want to start this by explaining the experiment and what happened during the experiment. The Milgram experiment was to determine the obedience of subjects, that was conducted by Stanley Milgram. This experiment was to test a subjects “conflict between obedience to authority and personal conscience” (McLeod, 2007). With this, Milgram was able to determine conformity of people to “go with the flow” and how the subject felt the need to be liked in the experiment, while being in control as the “authority” figure....

- The infamous Milgram experiment is one of the few experiments throughout the psychological community well known for being both extremely unethical and absolutely necessary. This well crafted experiment answered one basic question that in some ways spans across ethnic groups, class, gender, and ages: How could one person or group of people harm another person or group of people. It seems to be out of human nature, but from the aggression expressed from children fighting over a toy to the bitter hatred displayed by Nazi Germany towards several groups of people, humans harm other humans....

- This book is divided into sixteen chapters. Chapters 2 to 11 is all about the Stanford Prison Experiment (SPE). Though people know the SPE, in this book, he gives a detailed explanation of everything which is not mentioned in the publications. There were a group of applicants selected for this experiment, whose backgrounds were checked and had no psychological problems. These individuals were arrested one fine day from college, without a notice. These participants were then randomly divided into guards and prisoners....

- Aaron Keime Block #4 Obedience to Authority: Stanley Milgram (1963) Introduction Stanley Milgram in 1963 decided to do a sociological experiment that tested peoples devotion to authority. How far would people go if an authority figure ordered them to. Milgram took a random sample, meaning he took random people to take part in his experiment. He did so to get a generalized overview of the American population. These random people were to take part in one of the most influential social experiment in history....

- The Milgram Experiment (Hart) Stanley Milgram’s experiment in the way people respond to obedience is one of the most important experiments ever administered. The goal of Milgram’s experiment was to find the desire of the participants to shock a learner in a controlled situation. When the volunteer would be ordered to shock the wrong answers of the victims, Milgram was truly judging and studying how people respond to authority. Milgram discovered something both troubling and awe inspiring about the human race.... [tags: Stanley Milgram, Experiment, Obedience]

- Background Knowledge: Osmosis definition: Diffusion of water molecules through a semi permeable membrane from a higher concentration to a lower concentration until the concentration on both sides is equal. Osmosis in animal cells: The cell membrane is the partially permeable membrane in animal cells. If the cells were placed in distilled water they gain water, swell and burst. This is known as haemolysis. Osmosis in plant cells: The cellulose cell wall of plant cells is fully permeable. Therefore it’s the cell membrane of a plant cell which acts as the semi-permeable membrane, deciding what gets into and out of the cell.... [tags: Science Experiment]
