SOLUTIONS, ACID AND BASES

What is a solution?

• A substance being dissolved

• A mixture that has the same composition, color, density, and taste throughout

• A substance doing dissolving

• A type of gas like the air we breathe

What is a solute?

• A mixture that has the same composition, color, density, and taste throughout

• A substance doing dissolving

• A substance being dissolved

• A type of solid like brass or sterling silver

What is a solvent?

• A substance being dissolved

• A type of gas like the air we breathe

• A substance doing dissolving

• A mixture that has the same composition, color, density, and taste throughout

Which of the following can be a form of solution?

• Only liquid mixtures

• Only gaseous mixtures

• Only solid mixtures

• Gaseous, like the air we breathe, or solid, like brass and sterling silver

Which of the following is NOT a way to speed up the rate of the dissolving process when forming a solution?

• Stirring

• Increasing surface area

• Decreasing temperature

• Increasing temperature

What does stirring do to help speed up the dissolving process?

• Decreases the contact between solvent and solute

• Increases the temperature of the solvent

• Brings more solvent in contact with the solute

• Reduces the surface area of the solute

How does increasing the surface area of a solute help in the dissolving process?

• It decreases the amount of solvent needed

• It allows more solvent to come in contact with the solute

• It reduces the temperature of the solution

• It makes the solute harder to dissolve

What effect does increasing temperature have on the dissolving process of a solute in a solvent?

• It slows down the movement of particles

• It decreases the contact between solvent and solute

• It speeds up particles causing them to bump each other and break apart

• It increases the viscosity of the solvent

What is the definition of solubility?

• The ability of a solvent to dissolve a solute at any concentration

• The maximum amount of a solute that can be dissolved in a given amount of solvent at a temperature

• The process of increasing the temperature of a solution to dissolve more solute

• The measurement of how much solute is present in a solution regardless of the solvent amount

What does a concentrated solution refer to?

• A solution with a small amount of solute in the solvent

• A solution with a large amount of solvent in the solute

• A solution with a large amount of solute in the solvent

• A solution that can dissolve more solute at higher temperatures
