iron powder. Para-aminophenol crystallises out from the mother liquid which is subsequently centrifuged. Para-aminophenyl crystal is then reacted with acetic anhydride to produce pure paracetamol. The reactions are summarised as shown below: Lab scale manufacture Paracetamol can be easily prepared in the laboratory using phenol. Phenol reacts with sodium nitrate and separate para nitro phenol from outho nitro phenol. Then para nitro phenol is converted into para amino phenol using sodium

Raquel Johnson October 19‚ 2014 Solids: Recrystallization and Melting Points Organic Chemistry 2423 Lab Report: Recrystallization Abstract: The purpose of this lab was to purify an unknown compound by recrystallization. Taking an unknown compound and identifying it by purifying it from its impurities through the use of hot gravity filtration. Then to determine the unknown you were to take the melting point. An unknown compound was recrystallized from hot water to produce 0.99 grams (67% recovery)

Sterling Hayden AP Biology Mrs. Proehl 24 November 2014 I. Title Effect of Differing pH‚ Temperature‚ and Enzyme Concentration on Catalase Reaction Rate II. Introduction Enzymes are used to increase the rate of specific reactions in the body. Catalase‚ a specific enzyme‚ speeds the breakdown of hydrogen peroxide‚ a toxic chemical produced by cells in the body‚ into water and oxygen (Cain and others‚ 2010). The oxygen can be observed as bubbles coming from the reaction site. Catalase is found in many living tissues of organisms

Introduction and Purpose: This lab focuses on how weight affects the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s) respectively. The primary goal of this lab is to investigate and explain the relationship of these two factors. During the process of conducting this experiment‚ learning to design a lab will also be achieved. Research Question: What is the effect of weight on the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s)? Variable

Impurity Lab Report Aim: To find out the difference of the boiling point and melting point when adding impurity (salt) to water. Diagram: Method: 1.Set up the apparatus as shown in the diagram 2. Get a known amount of ice in the beaker (half full)‚ and a known amount of salt in another beaker 3. Measure the temperature (melting point) of the ice without adding any impurity (salt). 4. Measure the temperature (melting point) of the ice after adding the salt into the beaker. 5. Heat up

Lab Report Procedure 6.1: Perform Benedict’s test for reducing sugars. Introduction: Benedict’s tests allows for the detection of the presence of reducing sugars. All monosaccharides are reducing sugars since all of them have active carbonyl group. Some disaccharides that are exposed to a carbonyl group are also reducing sugars but less reactive than monosaccharides. By mixing the sugar solution with Benedict’s solution and heating them‚ a redox reaction will occur. The copper (II) sulphate

Lab Report Density Name: Period: Problem How do you calculate Density? What units did you use for volume‚ mass‚ and density? When the cubes are placed in water which one will sink 1st? What is the ranking of the cubes lightest (1) to heaviest (10)? Is it true that the cube with the most mass will have the most density? Hypothesis I think the 1st cube was aluminum I think the 2nd cube was steel I think the 3rd cube was brass I think the 4th cube was copper I think the 5th

transport is the movement of molecules from low concentration to high concentration against the concentration gradient. Energy is required for movement to occur. Water Balance- Salt concentration in blood depends on how much water is reabsorbed by kidneys and how much is excreted in urine. The concentration of salt in the blood can be higher if there is excess of sweating‚ not drinking enough water and eating salty food. Some drugs affect the volume of urine created. Caffeine causes more dilute urine
