then recrystallize the solute out of the cooled solvent. The formation of concentrated‚ pure crystals is possible in this recrystallization process if the appropriate cooling rate is applied to the solute and solvent mixture. Consequently‚ a purified‚ solid compound would be produced. Recrystallization involves dissolution of a solid in a solvent at elevated temperatures and the reformation of the crystals as the solution cools‚ allowing for impurities to remain in the solution. Once a solid has been

the time we return to the initial temperature‚ nearly all of the original material has formed crystals‚ which can be removed from the solvent by filtration. Now‚ suppose that the original solid contained small amounts of impurities. These would go into solution as well‚ but since the impurities are present only in small amounts‚ they remain soluble when the temperature is lowered again. Thus‚ the crystals‚ which come out of solution‚ are more pure than the original sample. This is the essence of purification

was employed to obtain the single crystal. The acetonitrile was taken in a beaker and the synthesized material was added to prepare the saturated solution. Then the solution was covered by a perforated sheet and kept separately for slow evaporation without any disturbance at room temperature. The crystal growth condition was optimized and grown crystals were purified by successive recrystallization process. Due to the spontaneous nucleation‚ colorless single crystals were obtained in a period of 15

Introduction Identification and classification of bacteria is important to make easier manipulation on the bacteria for various purposes such as for medical‚ research‚ developmental‚ and biotechnicalfieldsThe cell wall is the basis for classification of bacteria according to the Gram stain. Accordingto the chemical make up of bacterial cell wall‚ a staining procedure‚ Gram stain‚ helps usclassify bacteria into two subgroups‚ The cell wall can stain either positive or negative‚depending on its chemistry

to rebalance the energy field. The meridians generally begin at the finger tips and toes and end in major organs. Acupuncture uses needles to stimulate the meridians to release chemicals into the organs to balance the energy of the body and have a healing effect. EFT uses tapping instead of needles. Anyone can learn EFT. Tutorials‚ books and newsletters are readily available on the internet (See Gary Craig‚ Carol Look‚ Nick Ortner and others). This remarkable technique is easy to use and can be done

*Recrystallization- solid compounds Recrystallization - precipitation of a solid cpd. from a saturated solution in the form of crystals through cooling or evaporation -7 steps: 1) selecting the appropriate solvent 2) dissolving the solute 3) decolorizing the solution 4) removing suspended solids 5) crystallizing the solute 6) collecting and washing the crystals 7) drying the product - 2 Kinds of Impurities: 1) more soluble 2) less soluble than the main component - impure
