examples of gases soluble in water
A common example is the dissolving of carbon dioxide in water, resulting in carbonated water. When the beverage container is opened, a familiar hiss is heard as the carbon dioxide gas pressure is released, and some of the dissolved carbon dioxide is typically seen leaving solution in the form of small bubbles (Figure \(\PageIndex{3}\)).

The carbonation process involves exposing the beverage to a relatively high pressure of carbon dioxide gas and then sealing the beverage container, thus saturating the beverage with CO2 at this pressure.

The dissolution in a liquid, also known as fizz usually involves carbon dioxide under high pressure. Based on these properties, there are several examples of solubility. When the pressure is reduced, the carbon dioxide is released from the solution as small bubbles, which causes the solution to become effervescent, or fizzy. In addition to the pressure exerted by the atmosphere, divers are subjected to additional pressure due to the water above them, experiencing an increase of approximately 1 atm for each 10 m of depth. Use Henry’s law to determine the solubility of this gaseous solute when its pressure is 101.3 kPa (760 torr). Gases can even be soluble, like CO2 gas in liquid water. Solubilities of Gases in Water Methane, oxygen, carbon monoxide, nitrogen, and helium all have different solubilities in water, but all of them become less soluble with increasing temperature. To avoid DCS, divers must ascend from depths at relatively slow speeds (10 or 20 m/min) or otherwise make several decompression stops, pausing for several minutes at given depths during the ascent. For example, under similar conditions, the water solubility of oxygen is approximately three times greater than that of helium, but 100 times less than the solubility of chloromethane, CHCl 3. Common salt has a solubility in water of 359 grams per liter. Example \(\PageIndex{1}\): Application of Henry’s Law. 3-Alcohols Both ethyl alcohol (alcoholic beverages) and isopropyl alcohol (medical antiseptic) dissolve in water in a simple way. Missed the LibreFest? Other factors also affect the solubility of a given substance in a given solvent. Because we know both Cg and Pg, we can rearrange this expression to solve for k. Now we can use k to find the solubility at the lower pressure. Examples of Gas Solubility Analysis The Figure below shows the solubilities of some gas-air mixtures in water (partial pressure of solute vs. liquid mole fraction of solute). Any combination of units that yield to the constraints of dimensional analysis are acceptable. An example of solubility is the fact that sugar is very soluble in water. The absorption coefficient is defined as the volume of gas in mL that can be dissolved by 1 mL of a liquid solvent at the temperature of the experiment at one atmospheric pressure. This is one of the major impacts resulting from the thermal pollution of natural bodies of water. Decreased levels of dissolved oxygen may have serious consequences for the health of the water’s ecosystems and, in severe cases, can result in large-scale fish kills (Figure \(\PageIndex{2}\)). Marisa Alviar-Agnew (Sacramento City College). The solubility of gases in the liquid is expressed in terms of the absorption coefficient. Under pressure, though, gases become more soluble. An example of this would be carbonated drinks. A gas has neither a defined shape nor volume. Gases can form supersaturated solutions. Therefore, the air inhaled by a diver while submerged contains gases at the corresponding higher ambient pressure, and the concentrations of the gases dissolved in the diver’s blood are proportionally higher per Henry’s law. Legal. It is possible to add both cream and sugar to coffee because both are soluble in the drink. Drinks such as soda are bottled under pressure because gases are more soluble in this state. Gases are most soluble in water under high pressure and low temperature. Water vapor is an example of a gas. An example is liquid water. Gases that react chemically with water, such as \(HCl\) and the other hydrogen halides, \(H_2S\), and \(NH_3\), do not obey Henry’s law; all of these gases are much more soluble than predicted by Henry’s law. Another example of solubility is in the air: oxygen is soluble in nitrogen. A common example is the dissolving of carbon dioxide in water, resulting in carbonated water. When the temperature of a river, lake, or stream is raised abnormally high, usually due to the discharge of hot water from some industrial process, the solubility of oxygen in the water is decreased. Deviations from Henry’s law are observed when a chemical reaction takes place between the gaseous solute and the solvent. Decompression sickness (DCS), or “the bends,” is an effect of the increased pressure of the air inhaled by scuba divers when swimming underwater at considerable depths. Almost all the gases are soluble in water as well as in other liquids to a greater or lesser extent. This process is generally represented by the following reaction, where a pressurized dilute solution of carbonic acid in water releases gaseous carbon dioxide at decompression: \[H_2CO_{3(aq)} → H_2O_{(l)} + CO_{2(g)}\]. The bond between carbon and oxygen is not as polar as the bond between hydrogen and oxygen, but it is polar enough that carbon dioxide can dissolve in water. A 100.0 mL sample of water at 0 °C to an atmosphere containing a gaseous solute at 20.26 kPa (152 torr) resulted in the dissolution of 1.45 × 10−3 g of the solute. Temperature is one such factor, with gas solubility typically decreasing as temperature increases (Figure \(\PageIndex{1}\)). height="115" width="594" src="/@api/deki/files/59223/CNX_Chem_11_02_ammonia1_img.jpg" />.

However, in another liquid, such as methyl alcohol, it is only somewhat soluble. Gas solubility increases as the pressure of the gas increases. Noble gases are non-polar substances, so the only form of intermolecular forces that they have are London dispersion forces. Carbon dioxide is weakly soluble in water, therefore it separates into a gas when the pressure is released. CO2 is soluble because water molecules are attracted to these polar areas. A solid has a defined shape and volume. At 20 °C, the concentration of dissolved oxygen in water exposed to gaseous oxygen at a partial pressure of 101.3 kPa (760 torr) is 1.38 × 10−3 mol L−1. From the solubility plot, note that: at the same temperature (10 o C) HCl is more soluble than NH 3, which in turn is more soluble than SO 2. The chemical structures of the solute and solvent dictate the types of forces possible and, consequently, are important factors in determining solubility. Use Henry’s law to determine the solubility of oxygen when its partial pressure is 20.7 kPa (155 torr), the approximate pressure of oxygen in earth’s atmosphere.
