Test Tuffe Lab Report

Conclusion Throughout all the test tubes that were observed, it is simple to classify samples as mixtures, compounds, or elements by viewing the particles that make it up on a picture representation. It is not as uncomplicated as observing the physical substance. Test Tube A consisted of small black and white specks that could phyically be seperated when holding a magnet to the mixture. Because this is possible, it is a heterogenous mixture also because the seperation can easily be seen. Test Tube B is a homogenous mixture because another substance was dissolved into the water. Since it was dissolved, the molecules were spread out evenly. You could not tell it was a mixture by simply looking at …show more content…
We used evaporation to try and separate this mixture but it just left behind a white substance from the grains. The mixture remained together therefor it is heterogeneous. You can visualize this mixtures kind because of the different sized grains and color.

Test Tube E consisted of a clear and a yellow substance that did not combine. This is called an emulsion mixture since they are two liquids that do not normally combine. Because they cannot combine, they are heterogenous. By shaking Test Tube D, the two liquids look like they have combined into a light yellow substance, but soon after return to their previous state. This is because they must have differnt densitys. You could tell this was a heterogenous mixture just by looking at it because it didnnt even mix together.

Test Tube F is a heterogenous mixture since you could visually see the varying the sizes of particles and colors in the mixture. After observing the mixture in water, some of the peices went to the bottom of the beaker and the liquid had turned red. This still made the complete mixture a heterogenous mixture because the substance consists of differnt
