2016-6-22 that are not chemically combined is a mixture. The isolation of pure components of a mixture requires the separation of one component from another. Chemists have developed techniques for doing this. These methods take advantage of the differences in physical properties of the components. The techniques to be demonstrated in this laboratory are the following: Extraction. This uses a solvent to selectively dissolve one component of the solid mixture.

2010-8-26 original mixture. The separation scheme used to separate the mixture is based on differences in the physical properties (such as boiling point, melting point, solubility in a given solvent, etc.) of the three components. Chemists frequently illustrate a separation procedure by means of a flow chart as depicted below.

2016-5-27 In this lab, a mixture of three solids was separated to their individual components by extraction, based upon their acid-base properties. The acid (benzoic acid) reacted with NaOH to give a salt that moved from the organic phase to aqueous phase and thus was removed from the mixture. P-Nitroaniline being a base, reacted with HCl to give it’s

Filtration is a separation technique used to separate the components of a mixture containing an undissolved solid in a liquid. Filtration may be done cold or hot, using gravity or applying vacuum, using a Buchner or Hirsch funnel or a simple glass funnel . The exact method used depends on the purpose of the filtration, whether it is for the isolation of a solid from a mixture
