Mass Conservation in Solutions

What happens to salt when it is added to water and dissolves?

• It disappears.

• It evaporates.

• It remains in the water.

• It turns into gas.

After salt dissolves in water, what happens to its particles?

• They vanish.

• They stay in the water.

• They settle at the bottom.

• They evaporate.

What does the mass of the solution equal to?

• The mass of the solvent.

• The mass of the solute.

• The sum of the masses of the solute and solvent.

• Less than the mass of solute and solvent combined.

What is true for any solution?

• The solute disappears.

• The mass of the solution equals the total mass of solute and solvent.

• The solvent evaporates.

• The solute settles at the bottom.

What formula is given in the text for mass in a solution?

• Mass of solute × mass of solvent = mass of solution.

• Mass of solvent − mass of solute = mass of solution.

• Mass of solute + mass of solvent = mass of solution.

• Mass of solvent × mass of solute = mass of solution.

When salt dissolves in water, has any mass been lost?

• Yes.

• No.

• Only the mass of the salt.

• Only the mass of the water.

What is conserved when salt dissolves in water?

• The volume.

• The color.

• The mass.

• The texture.

Which of the following best describes what happens to the salt after it dissolves in water?

• It floats to the top.

• It spreads evenly throughout the water.

• It forms crystals.

• It evaporates into the air.

What does the term 'solute' refer to in the text?

• The liquid part of a solution.

• The substance being dissolved.

• The substance doing the dissolving.

• The gas in the solution.

What does the term 'solvent' refer to in the text?

• The substance being dissolved.

• The liquid part of a solution.

• The gas that forms in a solution.

• The solid in the solution.
