Aim: To see how different separation techniques separate different mixtures
Introduction: A mixture is a physical union of substances therefore being easy to separate. Most mixtures separate by physical means. There are different separation techniques to separate homogenous and heterogeneous mixtures.
Methods: Experiment A- The Separation of a Mixture of Sodium Chloride and Silica
First silica sodium chloride was placed in the beaker with a spatula 1/3 of water was added to the beaker
The water began to boil
It was removed from the Bunsen flame and poured into the filter funnel No sodium chloride mixture was passed. Only water and it was clear Some water was placed back into the filter paper to ensure that nothing does not go through The liquid in the beaker is placed in an evaporating dish It was placed on the Bunsen flame
As the water began to boil salt crystals begin to form around the sides of the dish Scrape the salt crystals from the sides as they begin to form so they can go to the middle of the dish
Once removed from heat the salt crystals was left
Experiment B- A Separation of Mixture of Iodine and Sodium Chloride
First Iodine and sodium chloride was placed into the test tube with a spatula...
