Unformatted text preview: -Weigh about 0.40g of unknown acid to the nearest 0.001g and carefully add to test tube-Record mass date in table 13.3-Tap test tube with finger so all unknown acid is down in the lauric acid-Insert test tube back into water bath and reheat water to 50 degrees C so lauric acid will melt-Raise test tube out of water and remove water bath-Take temperature readings every 30 seconds for 15 minutes-Stir sample with thermometer at a constant rate as the solution cools until stirring becomes impossible-Record temp-time data in table 13.4-Plot readings for temperature versus time to determine the freezing point of solution. CHE 102 Julianne Stiene Exp. 13 Flow Chart February 4, 2008-When completed, warm test tube gently in water bath until lauric acid melts-Remove thermometer and wipe-Pour molten lauric acid solution into jar marked USED LAUREN ACID-Perform calculations on back of table 13.5...
