Preparation of an Acetic Acid Ester Abstract: 14.1 g of octyl acetate were synthesized from the esterification process using 20.0 ml of acetic acid and 17.9 g of n-octanol. The theoretical yield was 23.8 g of octyl acetate. The percent yield was 59.2%. The purification of the final ester was confirmed by boiling point (186-199°C) and infrared index (nD=1.419). It was a colorless liquid that had a slight fragrance of orange and indescribable chemicals. The Infrared spectra confirmed ester

and it had a banana smell. Introduction Artificial flavoring is commonly used in the food that we eat today. For example‚ fruit flavoring is a chemical mixture that mimics a natural flavor as that of banana flavor from the synthesis of isoamyl acetate. Ester is the functional group‚ which is responsible for the distinctive odor and taste that artificial fruit flavoring has. Esters are derived from carboxylic acids. A carboxylic acid contains the –COOH group‚ and in an ester the hydrogen in this

Project 1: Polymer Ball Vivian Kim General Chemistry 2045L Introduction Our assignment in this project was to create a bouncy ball for a company using polyvinyl alcohol (PVA)‚ polyvinyl acetate solid and sodium borate‚ by varying the ration of ingredients and to determine the best recipe for our bouncy ball. The company chose the materials because of their odorless and nontoxic properties. PVA is a water-soluble synthetic polymer and has adhesive properties

polyvinyl acetate (PVAc) and we reacted them with sodium borate (borax). Polyvinyl acetate (PVA) is a water-soluble synthetic polymer. It has the idealized formula [CH2CH]n. Polyvinyl acetate (PVA) is a synthetic resin polymer. The chemical formula of this component is (C4H6O2)n. The last component is sodium borate (Borax). It is an important boron compound‚ a mineral‚ and a salt of boric acid. The chemical formula for sodium borate is (Na2B4O7·10H2O). In this experiment‚ both the sodium borate

Hydrochloric Acid + Sodium Thiosulphate "" sodium chloride + water + sulphur The reactants are both colourless‚ but one of the products‚ sulphur‚ is yellow‚ so we can use this fact to follow the rates of reaction. I am going to investigate how the concentration of the acid effects the speed of the reaction.

Sodium is a mineral that is present only in small quantities in most natural foods‚ but salt is added‚ often in large amounts‚ in food processing and by cooks to enhance flavor. Sodium is the predominant ion in extra cellular fluid. Sodium (Na) is the predominant cation in extra cellular fluid and its concentration is under tight homeostatic control. Excess dietary sodium is excreted in the urine. The kidney very efficiently reabsorbs the mineral when intakes are low or losses are excessive. Sodium

Sodium: Sodium is essential to all living beings Basic functions: Sodium has 3 main functions: it helps in the absorption of glucose and some amino acids in the small intestine‚ it is required for normal muscle and nerve function‚ and it aids in water balance. Glucose generated by digestion of starch or lactose is absorbed in the small intestine only by cotransport with sodium‚ a fact that has exceptionally important implications in medicine. Glucose and galactose are taken into the enterocyte by
