Gases in Solution Flashcards
Regarding the solubility of gases in solution (true or false):
SVP refers to the partial pressure of a vapour in equilibrium with its liquid
True
Regarding the solubility of gases in solution (true or false):
Henry’s law describes the relationship between amount of gas dissolved in solution and partial pressure
True
Regarding the solubility of gases in solution (true or false):
Henry’s law is independent of temperature
False. Henry’s law is at a fixed temperature.
Regarding the solubility of gases in solution (true or false):
All gases have the same solubility
False. Solubility is dependent on the gas. For example, nitrous oxide is more soluble than nitrogen.
Regarding the solubility of gases in solution (true or false):
The liquid need not be specified when stating Henry’s law
False. Henry’s law always specifies the gas and the liquid.
Regarding the Bunsen and Ostwald solubility coefficients (true or false):
The Bunsen and Ostwald are partition coefficients
False. Bunsen and Ostwald are solubility coefficients.
Regarding the Bunsen and Ostwald solubility coefficients (true or false):
The Bunsen coefficient is commonly used in anaesthetic practice
False. The Ostwald coefficient is more commonly used.
Regarding the Bunsen and Ostwald solubility coefficients (true or false):
The Bunsen coefficient must be corrected to STP
True
Regarding the Bunsen and Ostwald solubility coefficients (true or false):
Both Bunsen and Ostwald coefficients describe volumes of gas dissolved in unit volume of liquid
True
Regarding the Bunsen and Ostwald solubility coefficients (true or false):
The Ostwald coefficient is independent of pressure
False. The Ostwald coefficient is measured at a specified pressure.
Regarding the partition coefficient (true or false):
The partition coefficient refers to the ratio of a substance in two phases
True
Regarding the partition coefficient (true or false):
The partition coefficient is similar to the Ostwald coefficient
True
Regarding the partition coefficient (true or false):
The order of the phases need not be specified with the partition coefficient
False. The order needs to be specified. For example, the blood-gas partition coefficient is different from the gas-blood coefficient.
Regarding the partition coefficient (true or false):
One of the phases must be a gas
False. Both phases may be liquids.
Regarding the partition coefficient (true or false):
The temperature must be specified
True
