Chapter 6 Science Quiz

How is a mixture classisfied as either a colloid, suspension, or solution?

• Based on the size of its largest particles

• Based on the color of the mixture
• By the temperature at which it is stored
• According to the taste of the mixture

What is a solution?

• A solution is a mixture containing one solvent and solute with the same properties throughout

• A solution is a substance that cannot be dissolved in a liquid
• A solution is a mixture of two or more immiscible substances
• A solution is a solid substance dissolved in a liquid

What is the part of a solution that usually presents in

the largest amount and dissolves the other substance?

What is a solute?

• A solute is a type of gas
• A solute is a substance that is dissolved in a solvent to form a solution.
• A solute is a solid substance that cannot dissolve in a solvent
• A solute is a substance that separates from a solvent

Solvents and solutes must be liquids

• False

• True

What is a mixture containing small undissolved particles that don't settle out?

What are examples of colloids?

• shaving cream

• Fog

• alloys

• milk

What is a suspension?

• A suspension in which particles can be easily seen and easily separated

• A suspension is a liquid mixture where solid particles dissolve completely.
• A suspension is a homogeneous mixture with solid particles at the bottom.
• A suspension is a gas mixture where solid particles are evenly distributed.

How does a solution form?

• A solution forms when a solute is evaporated in a solvent.
• A solution forms when a solute is solidified in a solvent

• A solution forms when particles of the solute separate form each other and become surrounded by solvent particles

• A solution forms when a solute is filtered in a solvent.

What happens when NaCl is mixed with water?

• NaCl remains unchanged in water

• NaCl reacts with water to form a gas
• NaCl forms a covalent bond with water molecules
• NaCl dissociates into Na+ and Cl- ions that are attracted to charged polar water molecules
