Jolyne Piet CHM-221L-02 Lab #2: Experimental Design Isolation of Sucrose: 3.01 g Panacetin were weighed in a 125-mL Erlenmeyer flask‚ and 51mL dichloromethane were added to partially dissolve the Panacetin. The insoluble portion was gravity filtered and air dried to yield 0.45 g of sucrose (15.0 % of original Panacetin). Isolation of Aspirin: The organic filtrate was extracted through a separatory funnel with 32 mL 5% sodium bicarbonate to produce an aqueous layer and a dichloromethane layer

substances is. Magnetism as a separation method is done by taking any magnetic force (Electro magnets included) and moving it above an insoluble substance. Magnetism is only effective in insoluble substances. Examples of magnetic separation include the extraction of iron ore from surrounding silicate. Magnetic separation is also used to separate magnetic substances from waste water. Filtration is a technique that will separate a solid that has not yet dissolved in a liquid. Take a mixture of a solid and

This experiment was designed in order to extract caffeine from coffee grounds. In order to do this‚ filtration and extraction techniques with solvents such as calcium carbonate‚ magnesium sulfate‚ and dichloromethane were used1. Decaffeination is something that’s used around the world‚ and there is much discussion on the different methods that can be used. In this case‚ using solvents and heat was the preferred method in order to extract the caffeine. Decaffeination is often used to in order to prevent

The Separation and Purification of Organic Compounds Sunshine Marie Introduction Each year‚ many thousands of new or unknown organic compounds are prepared or extracted from natural sources such as plants‚ fungi and animals. In order to identify an unknown organic compound or the components of a mixture of organic compounds‚ it is necessary firstly to separate and purify the compounds. At any given temperature‚ a certain number of molecules of a substance in the liquid state have sufficient
