Acid-Base Titration Background Information A titration is a controlled addition of one substance into another substance. In an acid-base titration‚ the experimenter will add a base of known concentration to an acid of unknown concentration (or vice-versa). The goal of the titration is usually to use the substance of known concentration to determine the concentration of the other substance. In order to run a titration‚ the following materials are needed: • A buret filled with the base (or acid) of

Chapter 14 - Base Rate Base rate is the mean number of times an event occurs divided by the mean number of times it might occur. Representativeness is a bias when people wholly and exclusively rely on pre-conceived notions. Empirical evidence suggests that people formulate their judgments by relying on representativeness and neglect the base rate. This results in sub-optimal judgments and guesses. Given a plausible base rate‚ the anchoring of judgment of the probability of an outcome whilst putting

Lab Report: Acid and Base Indicator Lab The title of my lab report is “Acid and Base Indicator Lab” this lab is testing what household solutions area bases depending on what color they changed. You have to use the pH balance scale to determine Acid‚ Base‚ and Neutral. On this lab we used 7 different solutions to determine if it’s either base‚ acid‚ and neutral. These are ammonia‚ vinegar; drain cleaner‚ soft drink‚ baking soda‚ detergent‚ and lemon juice are the solutions that are going to be

When was care value base introduced? The care value base was introduced by the care sector consortium in 1992 from the national vocational qualification to support well known set of principles and values for care workers. Why was introduced? It was introduced so that people can receive their rights towards their care service and that they receive from their workers‚ and that there are fairness between every races and religions.

Derived Classes and Base Classes Mario Padilla IT/218 September 2‚ 2011 University of Phoenix/Axia College Derived Classes and Base Classes Considering that the ostrich is a flightless bird‚ it is reasonable to derive a class CHawk from CBird‚ but not a COstrich. This is mainly because the function fly () sets an altitude of 100 and‚ as everyone knows‚ the ostrich cannot fly. If we had to derive COstrich from CBird probably need to provide a function fly () to return 0‚ and this could

of the Enthalpy of an Acid-Base Reaction Abstract The purpose of this lab was to first‚ determine the specific heat capacity of a homemade calorimeter‚ and second‚ to calculate the enthalpy of reaction for an acid-base reaction between 6M KOH and 6M HNO3. To determine the specific heat capacity of the calorimeter‚ two differing temperatures of water were measured and volume was measured and mixed within the calorimeter. The enthalpy of reaction for an acid-base reaction was found by these

form of lower sales. Base on the view of culture metaphor‚ organizational culture is not a simple mirror of social reality but a framework for understanding (Slvesson). It is‚ however‚ important to reflect carefully upon the ideas‚ beliefs‚ and values that are important as subjects in organizational life and to distinguish between ‘key symbols’-symbols that play a vital role in terms of cognitive mapping‚ inspiring action‚ or summarizing emotions (Ortner‚ 1973). Base on this metaphor‚ sub goals
