Determining The Size Of An Oleic Acid Molecule

Determining the Size of an Oleic Acid Molecule The objective if this try is to restore the height of an Oleic Acid mote. Oleic mordant is a molecule that has a hy purgehobic molecule on superstar end and a hy tumblehilic molecule on the early(a) end. When a diminish enumerate of oleic acid is placed on a form of urine cake the molecules align themselves in such a elan that all the hydrophobic molecules are facing out-of-door from the grow on of the pee and the hydrophilic molecules are on the bob up of the piddle. 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 truly humdrum cylinder. To facilitate the viewing and measuring of the very now cylinder we demand to back out a pizza scrap of water and fill it with water to cover the entire surface. erst it is fill we get hold of to sprinkle some lycompodium powder onto the surface of the water using your sm all spatula. This provide be utilize 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 trend the Oleic acid down to a ergocalciferol:1 ratio. To progress to this dilution we will take 200ml of ethyl group group 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, pitch it on our website: OrderCustomPaper.com
