master's degree in horticulture in 1896. In the same year, he was invited to head the newly formed department of agriculture at the Tuskegee Institute in Alabama, where he spent the rest of his life. At Tuskegee he slowly built up a laboratory and researched ways to rebuild the exhausted land around the Institute. Carver found that soil which had apparently been ruined by over-cultivation of cotton and tobacco could be restored and that growing peanuts and sweet potatoes also improved the soil. In order to popularize these crops, he developed over 300 by-products, including cereals, oils, dyes, soaps, and new foods. At the same time, he conducted his remarkable school on wheels, a traveling classroom from which he taught Alabama farmers the basics of soil enrichment. When he died on June 5, 1943, he was one of America's most honored scientists, having brought prosperity to large areas of the impoverished South. 9 Which of the following is an accurate statement about Carver's childhood? (A) He was adopted by a man named Carver. (B) His parents died when he was still very young. He was born into a rich farming family in Missouri. D) Despite his youth, he fought to free slaves in the Civil War. 10871

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.
