Purpose
The purpose of the experiment was to see the effects of combining certain solutes and solvents. By conducting this experiment it is seen how solutions and mixtures relate to the six postulates of particle theory. When conducting this experiment, the particle theory was thought of, such as when you mechanically agitate a solution, particles move around and bump into each other, breaking up. The specific substances will be stated in the hypotheses. There were many things looked for when performing and observing the experiment. It was checked whether the substance was a homogenous or heterogenous mixture. Homogeneous mixture is when the substance has the same appearance and you can’t see the different substances. Heterogeneous mixture is when …show more content…
Light smell. Vinegar particles were left at the bottom. This means the solution was saturated. Homogeneous mixture.
Correct
Vinegar - Baking Soda
Baking soda dissolved in the vinegar. When baking soda was put in the beaker, the solution rose to half the height of the beaker. Many gas bubbles.
Homogeneous mixture.
Incorrect
Flour - Corn Starch
Corn starch dissolved in the flour. It seemed as if the corn starch moistened the flour.The flour and corn starch were both visible, even after being mechanically agitated.
Heterogeneous mixture.
Incorrect
Conclusion
The hypotheses about the solutions using water as a solvent were correct. The hypothesis was that the solutes would all dissolve in the water. This was correct, because water is the universal solvent. It is capable of dissolving more substances than any other solvent in the world. The hypotheses were wrong for the last two mixtures. It was hypothesized that these solutes would not dissolve in their respective solvents. However, they did. Next time, to avoid misjudgements and produce accurate hypotheses, the solubility of baking soda and corn starch in vinegar and flour, respectively, should be taken into
