Density Of Antifrreze-Water Mixture

DENSITY OF ANTIFREEZE- WATER MIXTURES In this experiment, several categorizations of piddle and ethene glycol (the major comp championnt of antifreeze) will be ready and their densities measured. A calibration curve will be generated by plotting density versus percent antifreeze, and this curve will be employ to determine the composition of an unknown sample assortment. WARNING: ethene glycol major component of antifreeze is a sweet tasting, barbarous liquid. Avoid unintentional ingestion by following sum of money laboratory safety measures. Step 1using a clean 10-ml pipet, make merry precisely 4.00, 3.50, 3.00, 2.50, and 2.00 ml of tap water to v farm test tubes. Step2: after rinsing the pipet with a scheming 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 generate a total added deal of 5.00 ml in for individu onlyy(prenominal)(prenominal) one tube. Step3: stir up each tube to ensure organized 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 five dollar bill samples by first rinsing the pipet with a small portion (ca. 1ml) of the sample and then transferring the precisely aliquot part 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 content before and after addition of the aliquot. For best results, fulfill all weighing in an uninterrupted sequence on the said(preno minal) balance. Step5: weigh a precisely ! measured volume (ca. 3ml) of an antifreeze/water mixture of unknown composition provided by the instructor. information abridgment Use the mass and volume data to calculate densities for the five standard samples and the unknown sample. On graph paper, plot mixture density versus % antifreeze for the standard samples. Draw the...If you want to get a full essay, order it on our website: OrderEssay.net
