EXPERIMENT 5 SEPARATION OF A MIXTURE INTO ITS COMPONENTS BY FRACTIONAL CRYSTALLIZATION Introduction: Fractional crystallization is one of the experimental techniques used to separate or purify mixture. Fractional crystallization makes use of the differences of solubility to separate the components of a mixture. Goals: Applying fractional crystallization to separate a mixture of salicylic acid and copper sulfate pentahydrate into its components. Calculate the percent of salicylic

Effect of enzyme concentration on rate of reaction Research question: is there a relationship between catalase concentration and the rate of reaction? Hypotheses: if the enzyme concentration is increased then the rate of reaction will increase. If the enzyme concentration is decreased then the rate of reaction will decrease. Controlled: temperature Independent: % catalyze concentration ( Dependent: rate of reaction (mm/s) Materials: Mortar and pestle Graduated cylinder Distilled

Kidney Disease- The kidney is a very vital organ to a human’s healthy existence. The pair of bean shaped organs are responsible for many important functions‚ they aid in the Urinary system as was as the Endocrine system. Their main functions are to filter wastes from the blood and secrete hormones. Due to the fact that the kidneys are responsible for maintaining regulation of the body ’s salt‚ potassium and acid content‚ they also play an important role in maintaining a proper homeostasis. According

benefits of kidney transplants. Kidney transplantation is the organ transplant of a kidney into a patient with end-stage renal disease. In the Early 1900’s European doctors attempted to save patients dying of renal failure by transplanting kidneys from various animals‚ including monkeys‚ pigs and goats. None of the recipients lived for more than a few days. And In the late 1940s and early 1950s‚ a team of doctors at Boston’s Peter Bent Brigham Hospital carried out a series of human kidney grafts

Purpose: To observe epithelial tissue by using a microscope to compare prepared slides. Introduction: Epithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers. This tissue is specialized to form the covering or lining of all internal and external body surfaces. Epithelial tissue can be divided into two groups depending on the number of layers of which it is composes. Epithelial tissue which is only one cell thick is known as

Synthesis of Butyl Benzoate Using Phase Transfer Catalysis The objective of the experiment is to synthesize the butly benzoate by nucleophilic substitution and characterize it by IR spectroscopy. The percent yield of the final product is determined after the synthesis. Procedures: 2.0 mL of 1-bromobutane‚ 3.0 g of sodium benzoate‚ 5.0 mL of water‚ 4 drops of Aliquat 336‚ and a boiling stone were placed in a 50mL round-bottomed flask. The reaction mixture was refluxed for 1 hour and the flask
