  • What does Henry's law state about the solubility of a gas in a liquid?
    Henry's law states that the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid.
  • How does increasing the pressure above a liquid affect the solubility of a gas?
    Increasing the pressure above a liquid increases the solubility of a gas because the added pressure forces more gas to dissolve in the liquid.
  • Does changing the pressure affect the solubility of solids or liquids?
    No, changes in pressure do not affect the solubility of solids or liquids, only gases.
  • What happens to the solubility of a gas in a liquid as temperature increases?
    As temperature increases, the solubility of a gas in a liquid decreases.
  • Why does gas escape from boiling water?
    Gas escapes from boiling water because increasing temperature decreases the solubility of the gas, causing it to leave the liquid.
  • How does temperature affect the solubility of solids in a solvent?
    Increasing the temperature increases the solubility of solids in a solvent, making them dissolve more readily.
  • What is the relationship between pressure and gas solubility according to Henry's law?
    The solubility of a gas increases as the partial pressure of the gas above the liquid increases.
  • If you apply more pressure to a closed container with gas above a liquid, what happens?
    More gas is forced to dissolve into the liquid, increasing its solubility.
  • What effect does increasing temperature have on the solubility of a solid?
    Increasing temperature causes the solubility of a solid to increase.
  • Does temperature affect the solubility of both gases and solids?
    Yes, temperature affects the solubility of both gases and solids, but in opposite ways.
  • What happens to a solid like a rock when boiled in water?
    The solid will eventually break down and dissolve in the solvent as temperature increases.
  • What is solubility?
    Solubility is the ability to dissolve a solute within a solvent.
  • Why does steam come out of boiling water?
    Steam is gas escaping from the water because its solubility decreases as temperature increases.
  • What two main relationships are important in Henry's law?
    The pressure-solubility relationship and the temperature-solubility relationship are important in Henry's law.
  • If you increase the pressure on a gas above a liquid, what happens to the amount of gas dissolved?
    The amount of gas dissolved in the liquid increases as pressure increases.
