Alka seltzer surface area experiment. See full list on sciencebuddies.

Alka seltzer surface area experiment. In this activity, students explore the reaction dynamics by varying temperature and surface area to observe the effects on dissolution rates. If the reaction is going faster . My hypothesis was proved correct in that an increase of surface area resulted in a much faster rate of dissolve for the Alka Seltzer tablets. The results clearly demonstrate that surface area has a significant impact on the dissolving rate of Alka-Seltzer tablets. By changing temperature and the surface area available for reaction, students will begin to see what factors chemical engineers can control to get the desired result. From your observations in Part 1, what change to the surface area made the reaction go faster? From your observations in Part 2, how did the temperature change affect how fast the reaction occurred? How does it work? Alka-Seltzer reacts with an acid to make carbon dioxide gas. In this lab, we’ll explore the effect on reaction rates of varying the surface area at constant temperature. For example, in 4 days ago · Discover how surface area and temperature affect Alka-Seltzer dissolution speed in this insightful experiment. After completing the experiment, it was clear that changing the amount of surface area of the alka seltzer drastically improved the rate of reaction, by almost 35%. Part I: Surface Area/Particle Size and Weathering Rate Materials – 2 beakers or cups, 2 Alka-Seltzer tablets, tap water, mortar & pestle Explore practical examples of examining the effect of surface area on reaction rates in chemistry projects. s2 rubg9z vbkz hpg gpi0h5yqm 7fira f9xc neauki 1pbfi oai0
