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.

2024 個體經濟學 0911 作業 請於 0918 上午8點前,在iLearning 上傳你的答案。 Each month a person consumes cosmetics (x1) and food (x2). The prices are p₁ = 100 and P21. Her monthly income is w = 8000. A department store is having a promotion this month. For every $2000 cash payment on cosmetics, the person can get a coupon of $200. So, if a person pays $4000 cash to buy cosmetics, she can get two $200 coupons. But if she pays $3999 cash to buy cosmetics, she gets only one $200 coupon. If she uses $3800 cash and one $200 coupon to buy cosmetics, she can get x₁ = 40 and one $200 coupon. The coupons expires at the end of this month and cannot be sold to others. x₁ and x2 can be any positive real number or 0. 1. Suppose that the coupon can be used on cosmetics only. Draw the person's budget con- straint. 2. Suppose that the coupon can be used on cosmetics or food. Draw the person's budget constraint. 3. Are both budget sets convex?
