To increase the percentage yield of ethyl ethanoate can be achieved by removing water or ester during esterification. Esterification is reversible reaction. For all reversible reactions‚ they have equilibrium constant‚ denoted by Kc. It should be the same if the reaction performed under same condition. In order to keep the Kc constant‚ the reaction will shift right

Discussion & Error Analysis: By examining the unknown alcohol’s H NMR spectra‚ it can be deduced that the alcohol is 1-(3-methoxyphenyl)ethanol. There are three peaks that have a shift of ~7.0-7.5‚ one with integration values of 1‚ 2‚ and 1.This shows that the alcohol is a meta-substituted benzene ring. The singlet peak with a chemical shift of~ 4.7 ppm with an integration of 1 is from the hydrogen on the OH group. The peak at ~ 1.7 ppm corresponds to the hydrogen of the carbon that is attached

Karl Fischer Titration Objective: To detrmine and analyze the moisture content of a given sample using Karl Fischer volumetric titration technique. Theory: Karl Fischer volumetric titration is used to detect analytically the moisture content present in samples. The iodine present in the Karl fischer reagent reacts stoichoimetrically with the amount of water present in the solution. For example water reacts with iodine in 1:1 mole ratio in the reaction: I2 + SO2 + H2O + 3Base + CH3OH → 2Base HI

historiographical debate over the controversy of “who bore chief responsibility” on who was solely to blame for the outbreak of war. The Treaty of Versailles is significant evidence to display how Germany was forced onto the conclusion that they caused the outbreak of war in Europe.
