Dustin Medina Plop-Plop Fizz-Fizz: How Does Surface Area and Temperature Affect Chemical Reaction Rates? The purpose of my science fair project was to find out how the chemical reactions rates of Alka- Seltzer tablets dissolving in water were affected by surface area and temperature. My hypothesis for this project was if the powdered Alka-Seltzer tablet is added to 30 water, then the chemical reaction rate will be faster than any other temperature or particle size tested. The constant variables in ...
All About Alka-Seltzer Charlotte Jerdal October 8, 2019 Unitas General Science Title 3 Abstract There are numerous ways to affect chemical reactions. An Alka-Seltzer tablet is medicine that has many uses. In this experiment, it will be used to determine if it is possible to change the length of a chemical reaction by changing the particle size of the solid reactant. The history of Alka-Seltzer, the chemistry of Alka-Seltzer, and the factors that affect the duration of a chemical reaction ...
Lava Lamp Experiment Material Needed: - Water - Oil (vegetable oil) - Food coloring - Alka-seltzer effervescent antacid tablets - Tall glass Instruction: 1. Fill the glass with 1 to 2 inches of water 2. Add food coloring. 3. Fill the rest of the glass with oil but stop at about 1 inch from the top so that it won't bubble over. 4. Drop an antacid tablet into the mixture and watch. The science behind it Alka Seltzer tablets ...

GNED 162 Introduction to Environmental Science Lab 7 (Scientific Method 2) Instructions: In this lab you will devise an experiment to answer two questions: 1. Does temperature play a role in the rate in which Alka-Seltzer will dissolve in water? 2. Does surface area play a role in the rate in which Alka-Seltzer will dissolve in water? All of the materials that you should need to conduct this experiment are provided on your lab tables. If you think you will ...
