10 Questions
According to Henry's law, what is the relationship between the solubility of an ideal gas and its partial pressure?
The solubility of an ideal gas is directly proportional to its partial pressure
In the context of Henry's law, what does the proportionality constant 'k' depend on?
The identities of both the gaseous solute and solvent, and the solution temperature
If the concentration of dissolved oxygen in water exposed to a partial pressure of 150 kPa is 0.002 mol L−1, what would be the new concentration if the partial pressure is reduced to 75 kPa, assuming ideal conditions according to Henry's law?
0.001 mol L−1
According to Henry's law, what happens to the solubility of a gas in a liquid as the partial pressure of the gas increases?
The solubility increases exponentially with the partial pressure
How does an increase in temperature affect the solubility of a gas in a liquid according to Henry's law?
The solubility decreases with increasing temperature
What is the relationship between the Henry’s law constant and the solubility of a gas in a liquid?
The lower the Henry’s law constant, the higher the solubility of the gas in the liquid
Why are supersaturated solutions of most solids in water prepared by cooling saturated solutions?
Cooling reduces the solubility of the solid in water, allowing excess solid to precipitate out and form a supersaturated solution.
Given the observation that ethanol is completely miscible with water and ethanethiol is soluble only to the extent of 1.5 g per 100 mL of water, what can be inferred about their molecular structures?
Ethanethiol exhibits stronger hydrogen bonding with water compared to ethanol.
What would be the most likely reason for CH4 to be the most soluble gas in water among the given options?
CH4 has a nonpolar covalent structure, which allows it to form weak London dispersion forces with water molecules.
How did the concentration of dissolved CO2 in the beverage change when the bottle was opened?
The concentration decreased due to CO2 escaping into the atmosphere.
