Reaction Rates: When Surface Area Matters!
Given the Alka-Seltzer mass and time values, let students calculate and record each average reaction rate in the data table provided in their worksheet. Let the students make a bar graph showing the average reaction rate, in grams/second, (y-axis) vs. surface area on the x-axis. As they cannot calculate the actual surface area of the tablet ...
The Alka Seltzer Reaction
In this activity, students will experiment with the reaction between Alka Seltzer tablets and water in different conditions. 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.
Part 3: Effects of surface area
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%. By adding surface area, the reaction occurred faster. For the experiment, I took three alka seltzer tablets and experimented with their surface area.

Unwrap 3 packets of Alka-Seltzer tablets so that there are 6 tablets. Fold one piece of scrap, wax, or parchment paper in half. Part 1. How does the tablet surface area affect how fast or slow the reaction will occur? Whole Tablet: As you start the stopwatch, drop one Alka-Seltzer tablet in the first cup of vinegar.
Alka-Seltzer Science: The Effect of Temperature on Reaction Time
Extra: Compare whole Alka-Seltzer tablets to pieces of Alka-Seltzer tablets. If there is a greater surface area (i.e., a tablet is broken up into more pieces), does the same amount of tablet result in the reaction happening faster or slower? Extra: You could turn this activity into a homemade lava lamp! To do this, you will want to use a tall ...

Surface Area
For this experiment our control variables were the amount of water, the amount of Alka Seltzer and the temperature of the water As seen on the graph below when the Alka Seltzer was crushed, in order to increase the surface area, the time at which it dissolved in water was visibly less than that of the crushed and whole Alka Seltzer tablets.

How Does Temperature and Particle Size Affect Alka-Seltzer Reaction Rates?
- The Alka Seltzer tablet in the cup with the ground up powder will have the fastest reaction time, as the increased surface area will allow for more contact between the tablet and the water. - The Alka Seltzer tablet in the cup with the chopped pieces will have a slightly slower reaction time than the ground up powder, but still faster than ...
Effect of Surface Area on the Dissolving of Alka-Seltzer Tablets
The experiment investigated two factors: surface area and the type of Alka-Seltzer tablet. The results clearly demonstrate that surface area has a significant impact on the dissolving rate of Alka-Seltzer tablets. The crushed Alka-Seltzer tablets dissolved faster than the whole tablets in both trials. This outcome aligns with our hypothesis ...
Can You Change the Rate of a Chemical Reaction by Changing the Particle
The main ingredients of Alka-Seltzer tablets are aspirin, citric acid, and sodium bicarbonate (NaHCO 3).When sodium bicarbonate dissolves in water, it dissociates (splits apart) into sodium (Na +) and bicarbonate (HCO 3 −) ions.The bicarbonate reacts with hydrogen ions (H +) from the citric acid to form carbon dioxide and water.The reaction is described by the following chemical equation:
