Purpose Use a standardized potassium permanganate solution to analyze an unknown iron solution by using redox titration. Theory Reduction-oxidation titration is an analytical method based on electrons transferring between an oxidizing agent and a reducing agent in solutions. Chemical analysis can be built on Redox titration if four criteria are met: a) The reaction is completed in a thermodynamically spontaneous condition. b) The reaction is fast enough to give an operational result instantly

mass per unit volume. (where P-density‚ m- mass and v- volume). Different materials usually have different densities and densities vary according to the pressure‚ temperature and purity of a substance. When measuring‚ there is always a small uncertainty or error and therefore no measurement is exact. Variables: Independent: the type of liquid used Dependant: the volume and density of the liquid Controlled: the same type of beaker as the mass of the beaker is never changed Hypothesis

Uncertainty will not be your undoing as a leader. However‚ your inability to give a clear directive in the midst of uncertainty might very well be the thing that takes you out or causes you to plateau early in your career. Uncertainty is simply a fact of leadership. Uncertainty calls for clarity. Be clear even when you are not certain. Lead confidently. Once a decision is made‚ move forward

IMSE 5655 Homework #1 and Case Study #1 Due: February 11th‚ 2013 Homework #1 1- Page 18‚ #5. Consider the supply chain involved when a customer orders a book from Amazon. Identify the push/pull boundary and two processes each in the push and pull phases. Push/pull view: processes in a SC are divided into two categories depending on whether they are executed in response to a customer order (pull) or in anticipation of a customer order (push) A customer orders a book

They are materialistic and after success and money. 4. Uncertainty avoidance: It is the extent to which the people feel threatened by unpredictable situations and have created beliefs and institutions that try to avoid these. Uncertainty avoidance is highly practice in Spain. People have rules for everything. Any change in the rule causes stress to the people. They are not risk takers at all. Whereas American society is uncertainty acceptance

variation in temperature between them. This in turn will keep the temperature of the solution constant. * Amount of pepsin: The pepsin used will be sourced from the same bottle for the entire experiment. This is to reduce any variation in levels of uncertainty of its concentration‚ which may affect the experiment. The pepsin will also be of the same temperature‚ as it will be

Monograph Review A Students Guide to Economics Written by Paul Heyne When you first thought about Economics‚ what did you think of? To me it was pretty much the study of money‚ as simple as that. I thought it would be interesting to ask a few people what their thoughts were and I heard many different definitions from as simple as “Money” from a family member to “To me it is the state of well being - money‚ housing‚ unemployment‚ industry etc.” told to me by a coworker. The true definition of Economics

Two measurements are made in this experiment. “L” the length of the string is measured using a meter stick which has a lowest gradation of 0.001m this gives a relative uncertainty of 0.0005m and an estimated absolute uncertainty of 0.005m due to human error measuring from the end of the string to the center of
