The objective if this experiment is to restore the height of an Oleic Acid molecule. Oleic acid is a molecule that has a hy purgehobic molecule on one end and a hydrophilic molecule on the other end. When a lessened amount of oleic acid is placed on a body of urine cake the molecules align themselves in such a elan that all the hydrophobic molecules are facing away from the surface of the pee and the hydrophilic molecules are on the surface of the water. 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 very humdrum cylinder.
To facilitate the viewing and measuring of the very flat cylinder we demand to take a pizza pan of water and fill it with water to cover the entire surface. Once it is fill we need to sprinkle some lycompodium powder onto the surface of the water using your small spatula. This provide be used 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 visible is to wreak a few crystals of potassium permanganate to darken the water.
We are as well as going to dilute the Oleic acid down to a ergocalciferol:1 ratio. To accomplish this dilution we will take 200ml of ethyl 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 experiment we need to determine the amount of solution 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, order it on our website: Ordercustompaper.com
