Enclosures: (1) Data Record (2) Data Treatment (3) Environment Impact Research After hours of vigorous examination‚ we have come to the conclusion that calcium chloride (CaCl2) would be the best deicer to use on a naval base over sodium chloride (NaCl) and ethylene glycol (C2H6O2). In order to melt ice‚ deicers lower the freezing point so that the ice melts at lower temperatures. CaCl2 has a freezing point depression of 5°C‚ whereas NaCl has only a 3°C depression‚ and ethylene

been watered down‚ to complete this task a sample of commercial vinegar was tested twice using titration and an average was taken of the two samples to give a base line to compare the potentially tampered samples against. Introduction Vinegar is a solution made from the fermentation of ethanol (CH3CH2OH)‚ which in turn was previously fermented from sugar. The fermentation of ethanol results in the production of acetic acid (CH3COOH). The typical pH of vinegar ranges anywhere from 2 to 3.5‚ although
