Grade 11
Term – 1
SY 2018-2019
Name:
Date :
Name of the Experiment: Release of gases
Aim/ Objective: To observe release of gases during a reaction.
Materials Used:
Pepsi; Diet Cola; Mentos; Volumetric Flask (250 ml)
Predict/Hypothesis:
Gases are one of the three states of matter. During the experiment when gases are released, the
process can get real violent real fast.
Safety Precautions:
The reaction is really violent and equipment must be handled carefully. In case of a spillage, inform
the laboratory teacher. Please review current Material Safety Data Sheets for additional safety,
handling, and disposal information.
Procedure:
1. Fill the flask with Pepsi and place it carefully in the container.
2. Add one piece of Mentos into the flask. Step away from the container and wait for the reaction to
proceed.
3. Observe the reaction and maintain a safe distance.
4. Repeat the experiment with diet cola and answer the following questions.
Observations and Questions:
Based on the performed experiment, answer the following questions.
1. Which cold drink had a more violent reaction? Why?
