Determining the Properties of Different Acids and Bases Yamin Liu November 16th‚ 2017 Chemistry 1021 Section: 427 Benton Smith Discussion of Results The goals of this experiment were to find the identities of four unknown compounds and to first determine the pH. We then were required to run a series of anion and cation tests to determine the composition of the unknown solutions. To get more knowledge about these solutions we ran a series of dilutions to see if

INVESTIGATORY PROJECT ABSTRACT: Adding oil to candle wax would soften it. The wax would melt at a lower temperature and the candle would drip more and burn down faster. The flame would also be larger than a flame on a candle with hard wax. Also‚ the flame would produce more soot and there would probably be an odor from whatever was cooked in the oil before it was used in the candle. Results of the tests showed that the candle made from 100 percent paraffin wax had the lowest melting rate‚ lowest

Cristhian Valor Organic Laboratory Pre-Lab 1. Main reaction sequence including side reaction products: 2. 3 Sentence Summary of the Experiment: The OH group on the benzene ring in salicyclic acid reacts with acetic anhydride to form an ester functional group. Thus the formation of acetylsalicyclic acid (aspirin) is referred to as an esterification reaction‚ which requires the presence of H+ (H2SO4 in our case). The technique used to purify the aspirin content is called crystallization

How does temperature affect the fermentation of yeast? In science‚ we stretched a balloon over the top of a bottle filled with sugar‚ warm water‚ and dry yeast. It inflated a little after a few minutes. We did the same thing with another bottle filled with sugar‚ cold water and dry yeast. The balloon didn ’t inflate. Apparently fermentation occurs more in hot temperatures than in cold. Why is this? Chemical reactions within yeast are facilitated by enzymes‚ which are large organic catalysts. Each
