Experiment 7 Experiment 7 The partition of Organic acid between Water and Organic solvent Objectives Understand the partition of a solute between two immiscible solvents. Introduction A chemical analysis that is performed primarily with the aid of volumetric glassware (e.g., pipets, burets, volumetric flasks) is called a volumetric analysis. For a volumetric analysis procedure, a known quantity or a carefully measured amount of one substance reacts with a to-be-determined amount of another substance with the reaction occurring in aqueous solution. The volumes of all solutions are carefully measured with volumetric glassware. The known amount of the substance for an analysis is generally measured and available in two ways: 1. As a primary standard: An accurate mass (and thus, moles) of a solid substance is measured on a balance, dissolved in water, and then reacted with the substance being analyzed. 2. As a standard solution: A measured number of moles of substance is present in a measured volume of solution - a solution of known concentration, generally expressed as the molar concentration (or molarity) of the substance. A measured volume of the standard solution then reacts with the substance being analyzed. The reaction of the known substance with the substance to be analyzed, occurring in aqueous solution, is generally conducted by a titration procedure. The titration procedure required a buret to dispense a liquid, called the titrant, into a flask containing the analyte. A reaction is complete when stoichiometric amounts of the reacting substances are combined. In a titration this is the stoichiometric point. In this experiment the stoichiometric point for the acid-base titration is detected using a phenolphthalein indicator. Phenolphthalein is colorless in an acidic solution but pink in a basic solution. The point in the titration at which the phenolphthalein changes color is called the endpoint of the indicator. Indicators are selected so that the stoichiometric point in the titration coincides (at approximately the same pH) with the endpoint of the indicator.

People from different countries view time differently. Take Mongolians, for example. They fresh grass for their animals. Due to the seasonally move from place to place, searching 1 extreme weather and the rough ground, it takes time to move around. The more quickly circumstances change, 2 their trips become. So, they adopt flexible schedules instead of strict ones. They often arrange appointments "before noon" or "at night" rather than set a certain time to meet. 3 they arrive within the specified period of time, they are considered "on time." 4 5 on a person is regarded as being However, this is very different from the practice in Japan, "late" if he or she shows up even one minute past the appointed time. This practice dates back to Japan's industrial revolution. At that time, factory employers demanded that employees time for shifts in order to meet tight production schedules. Apparently, people from different cultures view time in their own ways. Without a doubt, times may change, but culture runs deep. 1. (A) to (B) for (C) into (D) with 2.
