Properties of Gases
CHE101
Experiment date: 06/20 Write-up date: 06/21-06/22
Purpose: The purpose of this experiment is to examine different properties of gases in order to be able to identify them in a laboratory setting. I will be using Hydrochloric acid, mossy zinc, Bromothymol blue, limewater, Manganese, and Alka Seltzer, to test different properties of gases formed by chemical reactions. In order to extract the gas I will use several household products such as vinegar, baking soda, water, and hydrogen peroxide in order to create the gases to be tested. Materials:
Student Provided
1 Match
1 Toothpicks (or wooden splints)
1 Pie tin or similar
1 Marker pen
1 Household white vinegar
1 3% Hydrogen peroxide (H2O2) …show more content…
I wedged the test tune in with a bit of toilet paper.
c) I then filled the large stem pipet with water and placed it atop the rubber stopper.
d) I placed the well plate in a pie tin to prevent the overflow from getting everywhere.
e) After the water was replaced entirely with hydrogen I removed the wide mouthed pipet and placed my finger over the opening to prevent any gas from …show more content…
Bubbled rapidly, changed colors slightly to green
Alka Seltzer n/a n/a
Lots of pressure in the test tube, color change in limewater from clear to nearly milky, rapid small bubbles
Breath n/a n/a
Very large bubbles, color change from clear to nearly milky. n/a A) Give two reasons why we fill gas generator test tubes almost to the top with chemicals.
First we do this because maximizing the pressure in the tube will maximize gasses. Secondly because this causes there to be a shorter distance for the gases to traveled
B) What happens to the zinc in the hydrogen generation experiment?
The mossy zinc causes a reaction with the HCL to form hydrogen gas.
C) What happens in the oxygen generation experiment?
The manganese reacts with the hydrogen peroxide to form oxygen.
D) Write a balanced equation for the reaction between O2 and H2.
2H2 +O2--->2H2O
E) What is the function/purpose of the Bromothymol blue in the CO2 experiment?
The Bromothymol blue in the CO2 experiment is used to indicate how much CO2 is in the solution. It indicates this with a color
