Solution 2 Flashcards
What is solubility?
The ability of a substance to dissolve in a solvent.
True or False: Gases are always soluble in liquids.
False
What factors affect the solubility of a gas in a liquid?
Temperature, pressure, and the nature of the gas and liquid.
Fill in the blank: The solubility of gases generally ______ with increasing temperature.
decreases
What is Henry’s Law?
The principle that states the amount of gas that dissolves in a liquid is proportional to the partial pressure of that gas above the liquid.
Which gas is commonly used as an example of solubility in liquids?
Carbon dioxide
Multiple Choice: Which of the following increases the solubility of a gas in a liquid? A) Decrease in pressure B) Increase in temperature C) Increase in pressure D) Decrease in concentration
C) Increase in pressure
What is the effect of pressure on gas solubility?
Increasing pressure increases the solubility of a gas in a liquid.
True or False: The solubility of a gas is independent of the type of liquid used.
False
What is the term for the maximum amount of gas that can dissolve in a liquid at a given temperature and pressure?
Solubility limit
Fill in the blank: The solubility of gases in liquids is typically measured in ______ per liter.
milligrams
What is the significance of temperature in gas solubility?
Higher temperatures generally reduce the solubility of gases in liquids.
Multiple Choice: Which of the following gases has a higher solubility in water? A) Oxygen B) Nitrogen C) Carbon dioxide D) Helium
C) Carbon dioxide
What happens to the solubility of a gas when the temperature is lowered?
The solubility of the gas typically increases.
True or False: All gases have the same solubility in all liquids.
False
What role does molecular size play in gas solubility?
Larger gas molecules tend to have lower solubility in liquids.
Fill in the blank: The interaction between gas molecules and liquid molecules can affect ______.
solubility
What is the primary reason that carbonated beverages remain fizzy?
The high pressure of carbon dioxide keeps it dissolved in the liquid.
Multiple Choice: Which factor decreases the solubility of a gas in a liquid? A) Increased pressure B) Increased temperature C) Decreased temperature D) None of the above
B) Increased temperature
What is an example of a practical application of gas solubility?
Aquatic life depends on the solubility of oxygen in water.
True or False: Solubility is a static property and does not change with conditions.
False
What is the relationship between gas solubility and its molecular weight?
Generally, lighter gases have higher solubility in liquids.
Fill in the blank: The ______ of a gas can be affected by the presence of other solutes in a solution.
solubility
What is the general effect of salinity on the solubility of gases in seawater?
Increased salinity typically decreases gas solubility.
Multiple Choice: Which of the following statements is true? A) All gases are more soluble in warm water B) Cold water holds more dissolved gases C) Temperature has no effect on gas solubility D) Solubility is constant across different gases
B) Cold water holds more dissolved gases
