distribution should allow two immiscible solvents to separate with a portion of the solute distributed into each. Using a separatory funnel‚ acids were extracted with bases (NaOH)‚ and bases were extracted with acids (HCl). Gravity filtration‚ cold filtration‚ and hot filtration were all used in separating the compounds. Melting points were then observed in order to check for purity of the compounds. C. Structures –

separation of the unknown from the Panacetin by first isolating the sucrose and the aspirin. This process was done by starting with three grams of Panacetin and adding dichloromethane to dissolve and then separating the sucrose by filter-gravity filtration. The aspirin was then separated with the help of sodium hydroxide to isolate the unknown. From the values found‚ we were able to find percentages of sucrose‚ aspirin‚ and the unknown in relation to what is found on the labels of these tablets.

crystals. This was then heated and swirled vigorously until all is dissolved. Then remove and let cool slowly‚ while covered with a watch glass. Then it was placed in an ice bath to further crystallization. After crystallization is completed‚ a vacuum filtration system was used to separate crystals. These crystals were then dried‚ weighed‚ and melting point was determined.

Boiling Boiling is perhaps the most commonly used water purification technique in use today. While in normal households it is an efficient technique‚ it is unfeasible for industrial purposes mainly due to efficiency problems ← Filtration Filtration is also used for removing foreign particles from water. One major drawback of this purification process is that it cannot be used for removing foreign chemicals and impurities that are miscible with water. Since both the enlisted

Introduction People encounter esters everyday in both natural and synthesized forms. Esters are present in a variety of common compounds‚ from fragrances to animal fat (McMurry‚ 2008). Although these esters can undergo many different important reactions‚ this lab is particularly interested in the hydrolysis of esters into carboxylic

a liquid polar solvent‚ such as acetic acid‚ to dissolve solutes of the solid mixture. Because “like dissolves in like‚” the desired solute is dissolved into the solvent and the undesired solute is left in the solid phase. Through use of vacuum filtration‚ the solid and liquid can be separated‚ leaving the solid on the filter paper and the liquid in the container below. Liquid-liquid extraction is a method based on the varying
