Chemistry Quiz: Solutions and Solubility

What is a solution?

• A type of pure substance

• A type of gas mixture

• A homogeneous mixture composed of two or more substances

• A type of solid substance

What are the three types of solutions?

• saturated, unsaturated, and supersaturated

• solid, liquid, gas

• acidic, basic, neutral

• organic, inorganic, synthetic

What is a solute?

• The liquid in which a solute is dissolved.

• The temperature at which a substance dissolves.

• The process of dissolving a substance in a liquid.

• The substance that is dissolved in a solution.

What are the factors that affect solubility?

• Time of day, humidity, and altitude

• Temperature, pressure, and the nature of the solute and solvent

• Type of container, music playing, and the solute's zodiac sign

• Color, size, and shape of the solute

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

• The solubility of a solid in a liquid decreases at first, then increases as temperature continues to rise.

• As temperature increases, the solubility of a solid in a liquid decreases.

• Temperature has no effect on the solubility of a solid in a liquid.

• As temperature increases, the solubility of a solid in a liquid also increases.

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

• The solubility of a gas in a liquid remains constant regardless of pressure.

• Pressure has no effect on the solubility of a gas in a liquid.

• The solubility of a gas in a liquid increases with increasing pressure.

• The solubility of a gas in a liquid decreases with increasing pressure.

What is rate of dissolution?

• Boiling point of a liquid

• Speed of light

• Rate of dissolution

• Density of a substance

How does surface area affect the rate of dissolution?

• Surface area only affects the color of the solution

• Increasing surface area decreases the rate of dissolution

• The surface area affects the rate of dissolution by increasing the contact area between the solute and the solvent, leading to a faster dissolution process.

• Surface area has no effect on the rate of dissolution

What is concentration of a solution?

• The color of the solution

• Amount of solute present in a given amount of solvent or solution

• The volume of the solvent

• The temperature of the solution

How is the concentration of a solution usually expressed?

• Molarity, molality, or percentage

• Liters

• Grams

• Volume
