In this experiment‚ we used simple distillation and extraction to do synthesis of 1-bromobutane. The experiment was carried out by mixing 13.3 g of sodium bromide‚ 15 mL of water and 10 mL of n-butyl alcohol in a 100 mL round bottom flask. We cooled the mixture and added 11.5 mL of concentrated sulfuric acid. Then the mixture was heated at reflux with a short condenser for 45 minutes and then we drained out the condenser. We removed the condenser and distillation head was set up to set up the condenser

Potential Energy • Definition and Mathematics of Work • Calculating the Amount of Work Done by Forces • Potential Energy • Kinetic Energy • Mechanical Energy • Power An object can store energy as the result of its position. For example‚ the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly‚ a drawn bow is able to store energy as the result of its position. When assuming

Separating Acids and Neutral Compounds by Solvent Extraction Introduction The purpose of this experiment was to use solvent extraction techniques in order to separate a mixture consisting of a carboxylic acid (p-toulic acid)‚ a phenol (p-tert-butylphenol)‚ and a neutral compound (acetanilide). Extraction is the process of selectively dissolving one or more of the compounds of a mixture into an appropriate solvent‚ the solution that contains these dissolved compounds is called an extract (Manion
