The Effect of Temperature on the Solubility of Carbon Dioxide in Water Under Constant Pressure

5) 5 mL of sugar was added to the solution and a balloon was placed over the opening of the bottle to minimize the loss of any gas from the system.

What is the effect of temperature on the solubility of carbon dioxide gas in de-ionised water under constant pressure?

1. Carefully measure the volume of the trapped gas using the graduations (markings) on the side of the container.

1) Select a 60 mL Syringe Sealed from the Gas Syringe item under the Equipment menu. Set the volume to 20 mL in the Initial Gas Syringe Volume dialogue box.

Once inverted, built-up gas was released by turning the stopcock to its opened and closed positions. This was repeated for about four times in one minute intervals. Then the layers were allowed to settle until a separation between liquids could be observed. Due to the low density of the product, the top layer was to be extracted. The bottom layer was carefully and slowly extracted out of the separatory funnel.

Over the years Carbon Dioxide has been significantly increasing from human activity. CO2 has a concentration of about 400 ppmv (parts per million volume). Its concentration in the atmosphere was about 280 ppmv before the Industrial Revolution, now it has increased immensely to about 380 ppmv in 2006. Many have said Carbon Dioxide has been the main reason or cause of global warming; saying that if we produce too much of this greenhouse gas it can create a global climate change. Even though carbon dioxide affects the temperature of the atmosphere it also affects the acidity of water specifically in the ocean.

Alka-Seltzers were placed in 30°, 50°, 70°, 90° and 110° water.

5.Position gas collecting hose so it runs from reaction vessel through gas collecting box to opening of the graduated cylinder. The idea is that any gas coming through the tube will rise in the graduated cylinder and displace the water in it.

3.Secure the other end of the tube into the hole located on the rubber stopper

the stopcock to release the pressure. Close the stopcock, shake the funnel several times, and again release the pressure through the stopcock (see Technique 12, Section

As the temperature of water increases, the particles of solid Potassium chloride, KCl, which are absorbing energy from its surrounding, start moving more easily between the solution and its solid state because. According to the second law of thermodynamics, the particles will shift to the more disordered, more highly dispersed solution state. I predict that as the temperature of a KCl and water mixture increases, then the solubility of the KCl will also increase.

The volume of carbon dioxide gas produced from a reaction was measured in order to determine what carbonate sample was used. A gas assembly apparatus was used to capture the gas from a reaction between an unknown carbonate and 6M hydrochloric acid; three trials were performed. The mass of the unknown carbonate was determined, and the reaction occurred in a test tube. The volume of gas produced by the reaction was measured, and the partial pressure of carbon dioxide was calculated after the partial pressure of water vapor was determined using Dalton’s Law of Partial Pressures. The percent mass of carbon dioxide gas was then calculated, and the average mass percent was compared to the table of known carbonates. It was concluded that the unknown carbonate sample used in the reaction was magnesium carbonate.

When sodium carbonate was added to the separating funnel, effervescence occurred, inferring the release of carbon dioxide gas as a product of the neutralisation reaction. As the process continued, pressure built within the separating funnel, so it was vital to open the tap, after continuously inverting it.

Check whether it is ready or not, and then open the burette to start neutralize the acetic acid. (Check the progress by change in colour)

An experiment was conducted to test whether or not excess CO2 in the atmosphere had any effects on atmospheric temperature and water acidification. Two bottles were filled with tap water, and capped with a thermometer. One bottle had nothing added, the other had CO2 gas added. The bottles were placed near two desk lamps. The temperatures were recorded over a 1-hour period at 10-15 minute intervals, and the pH levels of the water in the bottles after the time were recorded. The experiment was conducted to obtain sample data on the effects of excess greenhouse gases such as CO2 in the atmosphere. The results in temperature showed a
