Introduction Esters are in a lot of natural products like flowers‚ spices and fruits. They are usually used in artificial flavorings. Carboxylic esters help amplify the sensory effect of esters. Isopentyl acetate is made from the direct esterification of acetic acid and isopentyl alcohol. The direct esterification of acetic acid and isopentyl alcohol is an equilibrium reaction that shifts the product to the side by using the excess of one of the starting reagents. Acetic acid usually used in excess

into account. The percent yields for the reactants in the equation are very far from 100% yield. In the case of water‚ the percent yield came out to be meaning there were at least 2 times to 4 times more water than there should be. The percent yield of oxygen came out to be ‚ around 2%‚ maybe higher considering uncertainty of what amount of oxygen there was suppose to be. The reaction was incomplete and had to be stopped because of time‚ which explains the very high percent yield of the water and

general formula Kw[Fex(C2O4)y]·zH2O. The variables x‚ y‚ and z were determined through the duration of the entire experiment. From 1.2000g of Fe(NH4)2(SO4)2 were synthesized 1.1###g of K3[FeIII(C2O4)3]·3H2O‚ owing for a percentage yield of 74.###%. A percentage yield of 11#.##% was also calculated‚ had the final product been K[FeIII(C2O4)2]·2H2O. This value was rejected because experimental errors are never to exceed theoretical values‚ which are taken on assumption that the experiment is carried

precipitation reaction. The second purpose is to use stoichiometry to calculate how much of a reactant will be used in a precipitation reaction‚ assuming that the amount of product is given‚ and to figure out the actual yield vs. the theoretical yield and to calculate the percent yield. The other purpose of this experiment is to practice the gravimetric analysis technique. The solution of Na2SO4 (0.5 M) and BaCl2 (0.1 M) were chosen in this experiment. The equation was used: Na2SO4 (aq) + BaCl2 (aq)
