Separation Lab Purpose: This lab was based on the separation of the components of a mixture. A mixture can be defined as a physical combination of two or more pure substances. Separation techniques are used to separate components that are not chemically combined. All of these techniques involve changes in the physical state of a chemical compound rather than chemical changes. Sea sand‚ table salt‚ and two other unknown substances will be separated using the separation techniques in order to demonstrate

Abstract: Experiment 55 consists of devising a separation and purification scheme for a three component mixture. The overall objective is to isolate in pure form two of the three compounds. This was done using extraction‚ solubility‚ crystallization and vacuum filtration. The experiment was carried out two times‚ both of which were successful. Background Information: This experiment combined all the knowledge of the previous labs performed throughout the semester. An unknown mixture containing

Mixture separation Lab I am one of the chemists assigned to design a cost effective procedure for handling the CARBOSE separation and recovery and hazardous waste disposal. The difficulties were trying to figure out is how we can effectively separate Carbose‚ sand‚ and naphthalene? The hypothesis we chose to solve this problem was if we put the mixture into water‚ alcohol‚ and mineral spirts‚ then in each solution one or more substance will not dissolve‚ will be visible‚ and also able to separate

Discussion: Continuous distillation‚ a form of distillation‚ is an ongoing separation in which a mixture is continuously (without interruption) fed into the process and separated fractions are removed continuously as output streams. A distillation is the separation or partial separation of a liquid feed mixture into components or fractions by selective boiling (or evaporation) and condensation. A distillation produces at least two output fractions. These fractions include at least one volatile
