Gas Solubility and Dissolution Concepts

The video tutorial explores the factors affecting solubility, focusing on how solids and gases dissolve in liquids. It explains that increasing temperature and agitation can help solids dissolve, while gases require lower temperatures and high pressure to remain dissolved. The tutorial uses examples like sugar in coffee and carbonated soda to illustrate these concepts. It concludes with a brief mention of solubility charts and their importance.

What is the process called when ions in a crystal break apart to dissolve?

• Dissociation

• Sublimation

• Evaporation

• Condensation

Which method can help a solid dissolve faster in a liquid?

• Reducing the solvent

• Adding more solute

• Increasing the temperature

• Decreasing the temperature

How does stirring affect the solubility of a solid in a liquid?

• It has no effect

• It increases solubility

• It changes the solute

• It decreases solubility

Why does crushing a solid increase its solubility?

• It changes the solvent

• It changes the chemical composition

• It decreases the surface area

• It increases the surface area

What happens to gas solubility when the temperature of the solvent is decreased?

• Gas solubility increases

• Gas solubility becomes zero

• Gas solubility decreases

• Gas solubility remains unchanged

Why should you avoid stirring a solution when dissolving a gas?

• It increases gas solubility

• It changes the gas

• It decreases gas solubility

• It has no effect

What is the effect of high pressure on the solubility of gases?

• It has no effect

• It decreases gas solubility

• It increases gas solubility

How does vapor pressure relate to gas solubility in a liquid?

• Higher vapor pressure increases solubility

• Vapor pressure changes the liquid

• Vapor pressure has no effect

• Lower vapor pressure increases solubility

What happens to a soda when the lid is left off for too long?

• It becomes more carbonated

• It goes flat
