Density Of Antifrreze-Water Mixture

DENSITY OF ANTIFREEZE- WATER MIXTURES In this experiment, several categorizations of body of water and ethene glycol (the major comp anent of antifreeze) will be rattling and their densities measured. A calibration curve will be generated by plotting density versus percent antifreeze, and this curve will be use up to determine the composition of an unknown sample mixing. WARNING: ethene glycol major component of antifreeze is a sweet tasting, felon liquid. Avoid unintentional ingestion by following beat laboratory safety measures. Step 1using a clean 10-ml pipet, bask precisely 4.00, 3.50, 3.00, 2.50, and 2.00 ml of tap water to v give out test tubes. Step2: after rinsing the pipet with a dandy quantity of antifreeze, transfer precisely 1.00, 1.50, 2.00, 2.50, and 3.00 ml of antifreeze to the 70-mm test tubes to intend a total added deal of 5.00 ml in for individu exclusivelyy(prenominal)(prenominal) one tube. Step3: stir up eac h tube to ensure methodical mixing of the liquids. The resultant mixtures are normally 20, 30, 40, 50, and 60% antifreeze by volume, respectively. Step4: weigh a precisely measured volume (ca. 3ml) of each of the tail fin samples by first rinsing the pipet with a small portion (ca. 1ml) of the sample and then transferring the precisely fractional to a preweighed beaker. Note: the weighing vessel needs non to be emptied after each addition; the raft of each aliquot is given by the difference in the mass of the beaker and its confine before and after addition of the aliquot. For best results, fulfill all weighing in an uninterrupted sequence on the like balance. Step5: weigh a precisely measured volume (ca. 3ml) of an antifreeze/water mixture of unknown composition provided by the instructor. information depth psychology Use the mass and volume data to calculate densities for the five standard samples and t he unknown sample. On graph paper, plot mixt! ure density versus % antifreeze for the standard samples. Draw the...If you want to get a full essay, order it on our website: OrderEssay.net
