Gases have several unique properties that make them distinct from other states of matter. In a lab setting, these properties can be observed and measured through various experiments and techniques.
One property of gases is their compressibility. Gases are able to be compressed, meaning that they can be squeezed into a smaller volume. This can be demonstrated through the use of a pressure gauge, which measures the pressure of a gas in a container. When the volume of the container is decreased, the pressure of the gas increases. Conversely, when the volume of the container is increased, the pressure of the gas decreases.
Another property of gases is their expansion. Gases are able to expand to fill the space available to them. This can be demonstrated through the use of a balloon. When a balloon is filled with a gas, it expands to fill the volume of the balloon. Similarly, if a gas is released into a container, it will expand to fill the entire container.
The buoyancy of gases is another notable property. Gases are less dense than liquids and solids, and as a result, they tend to rise to the top of a container. This can be demonstrated through the use of a flask filled with a gas and a liquid. The gas will rise to the top of the flask, while the liquid will remain at the bottom.
Gases also have low viscosity, meaning they are able to flow easily. This can be demonstrated through the use of a gas flow meter, which measures the flow rate of a gas through a pipe or tubing. The flow rate of a gas is typically much higher than that of a liquid, due to the low viscosity of gases.
Finally, gases are able to mix completely with other gases. This can be demonstrated through the use of a container with multiple gases. When the gases are released into the container, they will mix evenly and uniformly throughout the container.
Overall, the properties of gases make them unique and distinct from other states of matter. Through various experiments and techniques, these properties can be observed and measured in a lab setting.

If the flame flares up then it is probably oxygen. You also have the option to opt-out of these cookies. One way of detecting a gas is to observe its behavior in a chemical reaction. In the following experiment, a simple gas generation tube will be assembled with a test tube, a stopper having a short plastic tube through its middle, and a pipet bulb. This may take anywhere from 2 to 10 minutes.

Limewater does not react with other gases, such as hydrogen or oxygen, in a similar fashion. The syringe is set 15 mL marker volume and the pressure is recorded as 101. Then, carbon dioxide 60 mL was drawn into the syringe through the tube and its weight was measured. The limewater turned whiteish, so this means that I exhaled carbon dioxide. Place the gas assembly stopper with the hooked copper tube to the side of the well plate.
Write a balanced chemical equation describing the reaction of zinc and hydrochloric acid. Gases are composed of one or more elements. By changing the syringe 2 mL down for each run 4 times , the following volume and pressure reads. Extinguish both flames and working quickly, while the toothpick is still glowing, remove the pipet bulb from the gas generation tube and insert the toothpick into the pipet bulb. For the fourth trial, 98 milliliters of deionized water were measured out using a graduated cylinder and added to a beaker.
With the end still glowing, insert it into the pipet. Repeat steps 32 — 33 as necessary. The Bromothymol blue in the CO2 experiment is used to indicate how much CO2 is in the solution. Write a chemical equation for the reaction of CO2 and limewater Ca OH 2. Firmly place the stopper in the test tube. The syringe was then pulled out of the water and the new volume was recorded.

Experiment Identification of Gases Isolating Gases To test the gas or gases produced during a chemical reaction, the gas must first be captured. If your solution is a murky green, what might you assume about the solution? Fill an empty, clean, plastic pipet bulb with tap water from the cup that was set aside in Step 1. Materials: Matches Toothpicks Pie tin Marker White Vinegar Hydrogen peroxide Measuring spoons Straw Tissue paper Baking soda Test tubes 24 Well Plate Pipet Stoppers for the test tube Chemicals provided by Labpaq Procedure: Place a piece of mossy zinc in the test tube that contains diluted HCl. Experiment Identification of Gases 11.
Introduction: This lab focused on showing the reaction that takes place between zinc and iodine using only deionized water instead of acetic acid or vinegar as we did in the previous lab by adding acetic acid to zinc iodide. The gas slowly displaces the water in the pipet bulb; trickling down the outside of the test tube as gas takes its place in the pipet bulb. Did the BTB indicate presence of an acid or base? Firmly place the stopper in the test tube. Give two reasons why we fill the gas generator test tubes almost to the top with chemicals? Add 20 drops of Ca OH 2 to a clean, dry test tube. For the third trial, 98 milliliters of deionized water were measured in a graduated cylinder and then dumped into another Styrofoam cup. With gloves on, the thumb was placed over the opening of the burette to cap it and the burette was inverted in the beaker until it was over the magnesium roll.
This is done by heating compounds with the Bunsen burner and also by mixing compounds in the twenty four well plate. Place the tubber stopper with the gas delivery tube in the test tube and put the tube in the well plate. Test tube standing vertically in a well. For an exact listing of materials, refer to the Contents List included in your LabPaq kit. Carbon Dioxide Reaction Observations. Outline the procedures you would use to determine whether a gas sample was composed of hydrogen or oxygen. When collecting the data allow for the pressure to fluctuate and when it is….
Once the temperature of the water reached 45 degrees Celsius, the syringe was submerged in the water for two minutes. Support your answer with your observations in Data Table 2. The manganese seemed like a catalyst because it sped up the rate of the chemical reaction. Holding the test tube with the crushed antacid tablet over the sink, add the water from the pipet into the test tube. Outline the procedures you would use to determine whether a gas sample was composed of hydrogen or oxygen. Add 3 pieces of Zn mossy zinc to the test tube containing the HCl.
