Salt-Water Mixture Lab Report

Satisfactory Essays

Conclusion:
Hypothesis:
The hypothesis made was that if a salt-water mixture is heated, then eventually the water will no longer remain and only salt will be present. This inference is supported by a few facts and the observations recorded throughout the duration of this experiment. First off, salt-water is a homogeneous mixture, meaning that the composition is uniform throughout. In addition, water is a substance that evaporates when exposed to heat and turns into steam. The water changed state from a liquid to a gas because the water reached its boiling point, while the salt was still in solid form, just as it had been in the mixture. In simpler words, salt-water can be separated through evaporation because water has a lower boiling …show more content…

The class as a whole brainstormed together to come up with the materials as well. In conjunction, the class learned about the properties of certain substances, including the ones used in this lab. A few of the ones that were discussed were how iron is magnetic, the fact that salt is soluble in water, seeds contain air pockets that allow them to float, and that sand is more dense than water, causing it to sink. Using this information, the class was able to put together an efficient lab after learning about different separation methods listed above. The materials used during this lab were already provided, but some were newly introduced to the class. For example, the class learned how to set up and light a Bunsen burner, along with what a scoopula was and how it was used. Learning about these concepts and equipment during this lab will serve as an aid in future lab experiments as the class becomes more familiar with them. Overall, the purpose of this lab was accomplished because the class was able to put together a successful and efficient lab after learning about separation techniques.
Real-World:
One of the most important concepts discussed in this lab was the use of the scientific method. The scientific method is a series of steps followed to solve problems; collecting data, creating a hypothesis, testing the hypothesis and concluding the experiment. Although it is taught to be used in science-related
