Lava Lamp Lab - Conclusion
What might happen if I were to try to mix water, oil, food coloring and Alka seltzer. I had the hypothesis that if I mix all these things that it would make bubbles of gas. So I tried it. Using the materials provided in class, I found that water and oil don’t mix at all. The oil ended up on top of the water. Meanwhile the food coloring and water almost effortlessly mixed at first contact. After recording the mass of the alka seltzer, I dropped it right it into the test tube. As it crossed into the border of where the water met the oil, it reacted with the water to make the water bubble into the oil. As I started adding more and more Alka-seltzer, I observed that the bubbles went up and then down as it met the surface of the oil then to re-settle into its separate mixtures of water and oil. The reaction caused by …show more content…

I confirmed this once I put a rubber stopper on top of the test tube. With all the pressure being built up, the rubber stopper popped off once the pressure was high enough. The new gas was lifting the colored bubbles of water until it reached the surface to escape, leaving the denser liquid to sink.

The reason that the water and oil didnt mix, was in fact, fairly simple. The water was more dense than the oil. Density is measured by dividing mass and volume of any substance. Water, by having a higher density, ended up underneath the less dense oil. Another reason is because of the water has polar molecules while the oil is nonpolar, meaning that no matter how hard you try they will never ever mix and end up separate. In the end my hypothesis was correct, but failed to
