    October 17 & October 24‚ 2012 How is Aspirin Made? This lab is about synthesizing aspirin using a hotplate to heat the reaction. It involved vacuum filtration‚ recrystallization‚ and comparing the properties of aspirin with salicylic aspirin. The first thing we did in this lab was make a hot-water bath by putting a beaker with water on a hot plate. After measuring out 2.1 grams of salicylic acid and 3 ml of acetic anhydride‚ we mixed the two together‚ along with 3 drops of sulfuric acid. We

    Experimental Errors and Uncertainty No physical quantity can be measured with perfect certainty; there are always errors in any measurement. This means that if we measure some quantity and‚ then‚ repeat the measurement‚ we will almost certainly measure a different value the second time. How‚ then‚ can we know the “true” value of a physical quantity? The short answer is that we can’t. However‚ as we take greater care in our measurements and apply ever more refined experimental methods‚ we can reduce
