Acidity In Fatty Acid Essay
This experiment was carried out to determine the acidity number in fatty acid. The purpose of determining the acidity number in fatty acid is to obtain the refined oil samples with potential corrosion problem. In conjunction to that, the lower the value of acidity number in fatty acid of a refined oil sample, the better the quality of the refined oil sample. Hence, it is important to know the acidity number in fatty acid of a refined oil in order to distinguish the better one. This ensure one to have a healthier lifestyle.
This experiment determines the amount of sodium hydroxide, NaOH that needed to neutralize a certain measurement of acidity in fatty acid of a two gram of refined oil sample. NaOH played the role as a catalyst in this experiment. A catalyst is used to reduce the amount of the remains and help produce a larger yield of product. Furthermore, isopropanol that was added into the flask containing the refined oil sample is used to dissolve the oil. The flask was then heated to about 40 ̊C on a hot plate to prevent any formation of bubbles and also to completely dissolve the

H3O+ + OH- → H2O + H2O ------ (ChemPRIME, 2010)
When titration was carried out, fatty acid will react with sodium hydroxide and produce soap and glycerol. This process is known as saponification. The soap produced are sodium salt of long chain fatty acids.

Alternative Method: Measurement of metal-fatty acid complexes
This method is to detect complexes form by fatty acids and some metals (Cu/ Co) in spectrophotometry. Thus long duration and poorer sensitivity may occur. Yet this sensitivity can be improved by using radiochemical assay of complex of fatty acids with

This method of keeping the temperature probe cooled before measuring a new temperature was repeated throughout the entire experiment. Temperature data was collected for 180 s while swirling the temperature inside the calorimeter. The calorimeter still contained the warm water.

Separate Neutral Compounds
711 Words | 3 PagesIn this experiment, extraction was used as a separation technique to separate the acid, base, and neutral compounds. In extraction, two immiscible solvents with different polarities are used to dissolve and separate different solute components, so they form two distinct liquid layers. In this experiment, ethyl acetate, an organic solvent, and an aqueous solution, were used as the two immiscible solvents. The extraction solvent must be capable of dissolving one of the mixture components, without irreversibly reacting with it. While initially it seems as though the organic acid, base, and neutral compounds would never pass into the aqueous layer, the conjugate acid and base of the organic base and acid respectively are soluble in water.
Simple Condensation Reaction Report
864 Words | 4 PagesWeek 1 a simple condensation reaction between benzaldeyde and hydroxylamine produced the product benzaldehyde oxime that was found to be in oil. The percentage yield of the experiment is 64%. The 36% loss can be due to the solution needing to be neutralised with glacial acid, there was no way to tell if the reaction was neutralised, to help increase yield the use of pH indictor paper to indicate whether the reaction was neutralised. As by using a rotary evaporator to remove the organic solvent may have caused small amounts of the product to evaporate off as it a low melting point solid, if the water bath temperature was too high would have caused to melt and evaporate off. As melting point was not measured was unable to tell whether the product is pure.

The third step that you will need to do is to get the recording of the water’s temperature. The fourth step you will need to do is to place two tablets of Alka-Seltzer in the water. The fifth and final step that you will need to do is to get either a stopwatch or a timer and calculate the specific amount of time it will take for these tablets of Alka-Seltzer to completely

This is most likely due to the evaporation of the alcohol and the refraction of the light. 100 The amount of bubbles is so high that the liquid itself is barely visible in comparison with all of the
Gas Chromatography Lab Report
1545 Words | 7 PagesIf the sample to be analyzed is non-volatile, the techniques of derivatization or pyrolysis GC can be utilized. Gas chromatography (GC) has been an indispensable analytical technique in the application of fatty acid determinations in oilseed plant breeding, biosynthesis, and human metabolism. As well as the characterization of complex mixtures of geometric isomers when combined with other chromatographic separations and spectroscopic identification. Plant cultivators utilize GC as a more accurate and fast method to evaluate the differences and inheritance of fatty acids in oilseed crops such as rapeseed. flaxseed, and safflower.

Organic Chemistry Experiment 3: Chromic Acid Oxidation Reaction
702 Words | 3 PagesChromic acid is added continuously until a slight brownish colour solution persists, this is to make sure that complete oxidation of borneol in the experiment. Light petroleum was used to dissolve and extract the product from the aqueous layer twice, 15 mL each. Sodium carbonate and saturated solution were used to wash product and separate both aqueous and organic layer in the separating funnel. This is to increase the accuracy when flowing out the aqueous layer. The extracted organic layer was steam bathed to vaporize light petroleum which has low boiling point at 30-40˚C. Chromic acid is a more commonly used reagent for the oxidation of alcohols, it is a suspected carcinogen and generates hazardous waste.
Distillation Lab Report
1300 Words | 6 PagesThanks to the boiling chips, the heat is evenly distributed within the flask, which permits a more controlled boil and eliminates the possibility of the liquid in the flask bumping into the condenser[5]. The tedious distillation process is rather simple: the beverage evaporates in the distillation flask and, having no where else to go, enters the condensing tube, where it cools down and is converted back into liquid form. From there on, this liquid flows into the final container, a graduated cylinder [preferably in an ice bath]. The extracted distillate is otherwise known as ethanol, a clear, colorless, flammable liquid, produced through the process of glucose fermentation and frequently used as an intoxicating agent in liquors[6].
