PERIOD: # 4
ABSTRACT: A chemical reaction can be affected by many factors. The between Alka-Seltzer and Water is no different. In this experiment, the factors of temperature and reaction time will be tested
PROBLEM: How does temperature affect the reaction time of Alka-Seltzer?
HYPOTHESIS: If I change the temperature of the water, the time of the chemical reaction will increase or decrease depending on the temperature.
LIST OF MATERIALS:
8 ounces of Cold, Hot, and Room Temperature water
(3) 12 ounce cups
9 Alka-Seltzer Tablets
Pour the room temperature,cold, and hot water in to 3 separate glasses
Drop 1 Alka-Seltzer tablet in each glass and time the reaction
Repeat process 3 times
Room Temperature: The tablets dissolved at an average of 1 minute. Little to no residue left from the tablet. Room temperature had the 2nd fastest reaction time.
Hot Water: The tablets dissolved at a average of 30 seconds. No residue left from the tablet. Hot water had the fastest reaction times.
Cold Water: The tablets dissolved at an average of 2 minutes and 13 seconds. Some residue let from the tablet. Cold water had the slowest reaction time.
|Conclusion: The experiment proved my hypothesis correct. The reaction made by Alka-Seltzer and water did speed up or slow down, depending on which water was used.|
