Sand Chromatography Lab Report

In this Laboratory experiment, my lab partner Alexander and I were able to understand thoroughly the physical and chemical properties of salt (NaCl) and sand (SiO2). Followed by the right procedure we were able to design and test out the components of both NaCl and SiO2 in order to separate the unknown mixture that we were able to find out about. We were also given the task to provide the percent composition of the mixtures. Therefore, the separation of components among this experiment allowed us to obtain the right numbers for our calculations.
Mixture is defined as a substance made by mixing other substances together, in this case we will be dealing with salt and sand of course to undergo the process of separation. Distillation, Filtration, and Chromatography are known alternatives to separate the
We came to the conclusion that salt in water is a homogeneous mixture which readily does dissolve in water. While Sand is a heterogeneous mixture due to the many different particles that it contains, while in water it does not dissolve and therefore it remains separated. What physical properties will you use to separate this mixture? The physical properties that were used to separate this mixture were filtration and distillation among this experiment. Through distillation we were able to see the left over compound that was left after all the evaporation happened inside the heated beaker. Is the combination of salt and sand a new compound or a mixture? The combination of salt and sand will always be considered to be a mixture because it cannot be permanently changed, therefore it can always be brought back to the same state that it was started with, it cannot be a new compound due to the mixing of crystals with
