Dissolving and Solubility

What are the factors that affect the rate of dissolving?

• The factors that affect the rate of dissolving include temperature, surface area, agitation, and the nature of the solute and solvent.

• Distance from the equator

• Phase of the moon

• Color of the solute

How does temperature affect the solubility of a substance?

• Increasing temperature has no effect on the solubility of gas solutes in a solvent

• Increasing temperature decreases the solubility of both solid and gas solutes in a solvent

• Increasing temperature generally increases the solubility of solid solutes in a solvent, while it decreases the solubility of gas solutes in a solvent.

• Increasing temperature decreases the solubility of solid solutes in a solvent

Explain the relationship between solubility and pressure.

• The relationship between solubility and pressure is that as pressure increases, the solubility of gases in liquids also increases. This is described by Henry's law, which states that the solubility of a gas in a liquid is directly proportional to the partial pressure of that gas above the liquid.

• The relationship between solubility and pressure is that as pressure increases, the solubility of gases in liquids decreases exponentially.

• The relationship between solubility and pressure is that as pressure increases, the solubility of gases in liquids remains constant.

• The relationship between solubility and pressure is that as pressure increases, the solubility of gases in liquids decreases.

What is the effect of concentration on the dissolving process?

• Concentration has no effect on the rate of dissolving.

• Decreasing the concentration of a solute generally increases the rate of dissolving.

• Increasing the concentration of a solute generally increases the rate of dissolving.

• Increasing the concentration of a solute generally decreases the rate of dissolving.

Name one factor that can increase the rate of dissolving.

• Using a smaller container

• Stirring or agitation

• Adding more solute

• Decreasing the temperature

Describe how the solubility of a gas changes with an increase in temperature.

• Less soluble

• More soluble

• No change in solubility

• Becomes a solid

How does an increase in pressure affect the solubility of a gas in a liquid?

• An increase in pressure generally increases the solubility of a gas in a liquid.

• An increase in pressure has no effect on the solubility of a gas in a liquid.

• An increase in pressure decreases the solubility of a gas in a liquid.

• An increase in pressure only affects the color of the gas in a liquid.

What happens to the rate of dissolving when the concentration of the solvent is increased?

• The rate of dissolving decreases when the concentration of the solvent is increased.

• The rate of dissolving remains the same when the concentration of the solvent is increased.

• The rate of dissolving increases when the concentration of the solvent is increased.

• The rate of dissolving becomes unpredictable when the concentration of the solvent is increased.

Explain why stirring a solution can speed up the dissolving process.

• Stirring a solution can speed up the dissolving process by creating a chemical reaction between the solute and the solvent.

• Stirring a solution can speed up the dissolving process by reducing the surface area of the solute particles.

• Stirring a solution can speed up the dissolving process by increasing the temperature of the solvent.

• Stirring a solution can speed up the dissolving process by increasing the contact between the solute and the solvent, allowing for more efficient mixing and dissolving.

What is the relationship between the amount of solute and the rate of dissolving?

• The relationship between the amount of solute and the rate of dissolving is that as the amount of solute increases, the rate of dissolving decreases.

• The relationship between the amount of solute and the rate of dissolving is that as the amount of solute increases, the rate of dissolving also increases.

• The relationship between the amount of solute and the rate of dissolving is that there is no correlation between the two.

• The relationship between the amount of solute and the rate of dissolving is that as the amount of solute increases, the rate of dissolving remains constant.
