Figueroa, Malik 9D - Seperating Mixtures

1. Mixture

   • Separation Technique: Floatation
     • Result: Styrofoam beads begin to float
       • Separation Technique: Physical Separation
         • Result: Styrofoam beads are removed from mixture
           • Separation Technique: Physical Seperation
             • Result: Nickel is removed from mixture
               • Separation Technique: Filtration
                 • Result: Pebbles removed from mixtures
                   • Separation Technique: Decantation
                     • Result: AgCl separated from mixture
                       • Separation Technique: Fractional Distillation
                         • Result: Water and Alcohol seperated
                         • Fractional distillation will take advantage of the different boiling points of water and alcohol to separate them
                     • Using a seperating flask, the AgCl can be removed since it sinks and forms it's own layer
                 • The small pebbles will be caught by the filter paper, but the water, AgCl and alcohol can pass
             • The magnet attracts the nickel, allowing it's removal from the mixture
         • Physically seperating the styrofoam beads with a spoon will be easier, as they are all floating
     • Substances with lower density will float up, allowing easy physical seperation
   • Styrofoam beads
     • Floats
   • Water
     • Higher boiling point than alcohol
   • Alcohol
     • Lower boiling point than water
   • Nickel

   • Pebbles
     • Sinks, insoluble
   • AgCl
     • Dense precipitate
