Chemistry lab on saturated and unsaturated fats Essay

This experiment has also been trialled using KMnO4(aq) (0.0005 breakwater dm ) as the indicator. This turns from purple to colourless maculation unsaturation is still present. The procedure is the same as for bromine water, but portions of the potassium permanganate are added with swirling until the mixture fails to discover a colourless solution. The mixture requires more(prenominal) and more swirling as the amount of potassium permanganate increases. Warming fats in the Volasil using a beaker of hot water helps the fat dissolve and also speeds up the reaction.see morechemistry matriculationThis experiment should be done in a fume-cupboard with ready filled burettes. ground theorySaturation and unsaturation.Classic chemistry experiments21 sanctuaryWear eye protection.Answers1. Depends on what is supplied.2. measure the fats and oils and calculating the exact amount of bromine water used per mole.3. Unsaturated compounds contain double covalent bonds.Classic chemistry experiment sUnsaturationin fats and oilsIntroductionAdvertisements often refer to unsaturated fats and oils. This experiment gives a resemblance of unsaturation in various oils.Burettecontainingbromine waterConical flaskOil and VolasilWhite coverWhat to recordVolume of bromine water required for each oil.What to do1. Using a pap pipette, add five drops of olive oil to 5 cm of Volasil in a conical flask. 32. Use a burette filled with a dilute solution of bromine water (0.02 mol dm ) (Harmful and irritant). Read the burette.3. Run the bromine water slowly into the oil solution. Shake vigorously after(prenominal) each addition. The yellow colour of bromine disappears as bromine reacts with the oil. Continue adding bromine water to gain a permanent yellow colour. 4. Read the burette. Subtract to find the volume of bromine water involve in the titration.5. Repeat the experiment with five drops of cooking oil (vegetable) and five drops of cooking oil (animal).SafetyWear eye protection.Question s1. Which sample is the most saturated and which is the most unsaturated? 2. This comparison is only approximate. How could the method acting be improved? 3. What does unsaturated mean?
