Question

classify each of the events based on whether the solubility of the gas will increase, decrease, or stay the same.
gas solubility increases gas solubility decreases gas solubility does not change
answer bank
co₂ in an opened can of soda as it warms to room temperature. the partial pressure of an anesthetic gas is increased.
o₂ in the blood of a person who is placed in a hyperbaric chamber the temperature is decreased.
the pressure of a gas over a solvent is decreased.

Explanation:

Step1: Recall gas - solubility rules

Gas solubility in a liquid is inversely proportional to temperature and directly proportional to pressure.

Step2: Analyze each event

• For "CO₂ in an opened can of soda as it warms to room temperature": As temperature increases, gas solubility decreases.
• For "The partial pressure of an anesthetic gas is increased": As partial - pressure increases, gas solubility increases.
• For "O₂ in the blood of a person who is placed in a hyperbaric chamber": In a hyperbaric chamber, pressure is increased, so gas solubility increases.
• For "The temperature is decreased": As temperature decreases, gas solubility increases.
• For "The pressure of a gas over a solvent is decreased": As pressure decreases, gas solubility decreases.

Answer:

Gas solubility increases: The partial pressure of an anesthetic gas is increased, O₂ in the blood of a person who is placed in a hyperbaric chamber, The temperature is decreased
Gas solubility decreases: CO₂ in an opened can of soda as it warms to room temperature, The pressure of a gas over a solvent is decreased
Gas solubility does not change: None of the given events fit this category.
