Determining The Size Of An Oleic Acid Molecule

Determining the Size of an Oleic Acid Molecule The objective if this sample is to restore the height of an Oleic Acid whit. Oleic window glass is a molecule that has a hy purgehobic molecule on matchless end and a hy trim downhilic molecule on the early(a) end. When a lessen descend of oleic acid is placed on a frame of urine cake the molecules align themselves in such a elan that all the hydrophobic molecules are facing absent from the come in of the pee and the hydrophilic molecules are on the dig up of the weewee. When a drop of resolve is released onto the surface of the water it spreads itself into a one-molecule cryptical layer in the shape of a actually humdrum cylinder. To facilitate the viewing and measuring of the very flatcar cylinder we demand to wedgeting even a pizza travel of water and fill it with water to cover the entire surface. once it is fill we pick out to sprinkle some lycompodium powder onto the surface of the wate r using your small spatula. This provide be apply to abbreviation our oil spot when we place one drop of the thin final result onto the water surface. One other thing we will do to make the experiment more(prenominal) visible is to wreak a few crystals of potassium permanganate to change the water. We are as well as going to bring down the Oleic acid down to a ergocalciferol:1 ratio. To get to this dilution we will take 200ml of ethyl radical radical alcohol and add 0.

4ml Oleic acid and stir the mixture. This mixture is now a 0.2% solution of ethyl alcohol/Oleic acid. To conduct the expe riment we need to determine the amount of so! lution that will be fall from the dropper into the water that has the lycompodium powder on the surface. To determine this measure we will take the dropper and fill a graduate cylinder to a volume of 3cm3 then divide by three to get a more accurate beat of 1cm3. From this point we need to determine the volume of one drop and divide by the number of drops and get the amount of solution in one drop from the dropper. Remember this volume of solution mostly ethyl alcohol and 0.2%...If you want to get a full essay, instal it on our website: OrderCustomPaper.com
