Solutions (Concentration and Dissolving) V2

What is the difference between a saturated solution and an unsaturated solution?

• A saturated solution can dissolve more solute than an unsaturated solution.

• A saturated solution contains the maximum amount of solute that can dissolve at a given temperature, while an unsaturated solution can still dissolve more solute.

• An unsaturated solution contains the maximum amount of solute that can dissolve at a given temperature, while a saturated solution can still dissolve more solute.

• Both saturated and unsaturated solutions contain the same amount of solute.

What is the term for a solution that contains more solute than it can theoretically hold at a given temperature?

• Saturated solution

• Unsaturated solution

• Supersaturated solution

• Concentrated solution

What does it mean if two solutions have the same concentration?

• They have different amounts of solute per unit volume of solvent.

• They have the same amount of solute per unit volume of solvent.

• They have the same temperature and pressure.

• They are both saturated solutions.

What is a solute?

• A substance that is dissolved in a solvent to form a solution.

• A type of solvent used in chemical reactions.

• A mixture of two or more substances that are not chemically combined.

• A solid that forms from a solution during a chemical reaction.

What is the role of agitation in the dissolving process?

• Agitation helps to disperse solute particles throughout the solvent, speeding up the dissolving process.

• Agitation slows down the dissolving process by compacting solute particles.

• Agitation has no effect on the dissolving process at all.

• Agitation only affects the temperature of the solvent, not the dissolving rate.

Does stirring a solute into a solvent affect the rate of dissolving?

• Yes, stirring increases the rate of dissolving by distributing the solute particles more evenly.

• No, stirring has no effect on the rate of dissolving.

• Stirring decreases the rate of dissolving by compacting the solute particles.

• Stirring only affects the temperature of the solvent, not the rate of dissolving.

What effect does temperature have on the solubility of most solids?

• Increasing the temperature decreases the solubility of most solid solutes.

• Increasing the temperature has no effect on the solubility of most solid solutes.

• Generally, increasing the temperature increases the solubility of most solid solutes.

• Increasing the temperature only affects the solubility of gases.

What is a solvent?

• A substance that dissolves a solute, resulting in a solution.

• A type of chemical reaction that occurs in liquids.

• A solid that can be mixed with liquids to form a solution.

• A gas that can dissolve in water to form an acid.

What is the universal solvent?

• Oil

• Ethanol

• Water

• Glycerin

What is the definition of concentration in a solution?

• Concentration refers to the amount of solute present in a given volume of solvent or solution.

• Concentration is the total mass of the solution divided by its volume.

• Concentration is the temperature at which a solution boils.

• Concentration is the measure of how much solvent is present in a solution.
