The Expirement that the chemist will be conducting includes the following materials: hot water, room tepmerature water, cold water, and regular Alka Seltzer tablets. Research on Alka Seltzer in previous expirements shows that it dissolves faster in hotter temperatures of water. It also shows in previous expirements that Alka Seltzer dissolves slower in colder temperatures of water rather than hotter temoeratures. Alka Seltzer is an antacid that contains aspirin. It is made in tablets that dissolve in water to give a fizzy reaction.…
The law of conservation of mass states that matter can be neither created nor destroyed during a chemical reaction, so when the tablet dissolved into the water the tablets turned from a solid into a liquid while mixing in with the water and releasing carbon dioxide. The tablets took a while to dissolve as the tablet had sodium in it, which when placed in water the dissolving of the tablet causes a strong exothermic reaction as the sodium responds with water and released carbon…
Essentially the warm water will run through the coffee beans and extract its properties. The flavor of the coffee beans would disperse into the water. The water would change color and smell like the coffee beans as these properties are drained from the coffee beans.…
Second remove the sand by adding the mixture to hot water, which the other two substances are soluble.…
When the tablet went into the water it made the water start spinning. The dry ice started steaming up because when dry ice and water react they start producing carbon dioxide gasses. Hydrochloric acid and dry ice mixed and the water started to change colors from yellow to light green to dark green to dark blue/purple. The dry ice started breaking into chunks and when more hydrochloric acid is added the dry ice disappeared into the solution.…
I knew that the more water in the glass would make the Alka-Seltzer dissolve slower but the warmer temperature would speed it up a little bit.…
In this lab, the results did not formulate as what was supposed to happen. Theoretically, the tap water would work the fastest because there was no environmental factors affecting the outcome. As the temperature of the hydrochloric acid was raised, the enzyme’s speed should have slowed. In the results, the ice water worked the fastest and the 50° of HCL was the slowest. But the result of the 38°C was off by at least 90 ml/min in comparison to the tap water when it was supposed to work slower.…
The only difference between the two is that water only had gelatin in it and cold water had gelatin and fresh pineapple juice in it. After two minutes the water that only contained gelatin in it solidify. Cold water that contain gelatin and fresh pineapple juice solidifies after 15 minutes, however, there were liquid on the top. Maybe if the cold water tube stayed in the ice water for a little longer the gelatin would have completely solidify. Hot water contain gelatin and fresh pineapple juice. The table 2 shows that after 15 minutes gelatin was solidified with a small portion of gelatin in it. Before the gelatin was added the tube that was labeled hot water was heated to 70°C for five minutes. With the pineapple juice in heat it cause the enzyme to denature the function of the enzyme cease. If the fresh pineapple juice was not heated the gelatin would have not solidified. Although the hot water tube solidify it was not completely solidified because there were still substances on the top. Maybe if the hot water tube was left longer in the ice it would have completely…
After the experiment, I thought and considered that my hypothesis was correct. It had been that the half crushed tablet had dissolved much faster then the other types of tablet. By increasing the surface area the reaction rate of the tablet will dissolve much faster.…
During a warm soak, the magnesium sulfate is slowly absorbed into the skin, helping to draw toxins out of the body. This…
6.) Does the temperature of the water make a difference in the amount of time it takes the tablet to dissolve?…
My hypothesis is if the water temperature is hot then the life saver will dissolve quicker because the hot water has a greater chemical effect on the life saver than the other temperatures. I believe this is because the hot water is creating a chemical change and is changing the solid object into a liquid.…
After testing my hypothesis, my results were proven right. When comparing how the Alka-Seltzer tablet dissolved in the hot temperature water and how it dissolved in the cold temperature water. It showed that the hotter the temperature of the H2O was the faster the Alka-Seltzer tablet dissolved.…
My hypothesis is that the Alka-Seltzer tablet will dissolve fastest in salt water, and the slowest in cold water. I think it will dissolve fastest in salt water because of the salt. I think it will dissolve slowest in cold water because the cold water doesn’t help the Alka-Seltzer dissolve faster.…
This lesson will have students investigating the effect of temperature on a simple chemical reaction, effervescent tablets bubbling in water. (Be sure to use uncoated tablets.) The students will design an experiment to test their hypotheses and gather data to create and support their conclusions. We will provide students with warm water, cold water, and room-temperature tap water. Students will have access to various probes, including the temperature probe. We expect students will measure the temperature of the different samples of water before adding the tablets. We will have a discussion with students about what they think those bubbles are prior to letting them design and conduct their experiments. Some may choose to measure CO2 as well, after this discussion.…
