If you have a solution of salt water, what is the solvent in this solution?

• Water

• Salt and Water

• Salt

• Neither are the solvent

A solution is saturated at 25°C. It is then slowly cooled to 20°C with no change to the appearance of the liquid. What term would be associated with this solution?

• saturated

• unsaturated

• supersaturated

• oversaturated

A saturated solution is made by dissolving 36.8 g of a solid in 200 mL of water. A second solution is made by dissolving 19.1 g of the same solid in 100 mL of water. How would this solution be classified?

• unsaturated

• saturated

• supersaturated

• hypersaturated

Gasses are most soluble in liquids at:

• High temperature and low pressure

• Low temperature and low pressure

• High temperature and high pressure

• Low temperature and high pressure

Which of the following would NOT increase the rate at which a solid dissolves?

• decreasing the temperature

• crushing the solid

• stirring

• increasing the temperature

Why does crushing a solid increase the speed at which the solid dissolves?

• Crushing causes the solute particles to separate from one another and spread out more quickly among the solvent particles.

• Crushing causes particles to move more quickly, causing them to spread out more quickly.

• Crushing increases the amount of contact between the solute and the solvent.

• Crushing does not affect the speed at which a solid dissolves.

Which will increase the amount of a solid solute that can be dissolved in a solution?

• Increase temperature

• Decrease temperature

• Increase pressure

• Decrease pressure

It refers to the process of preparing a less concentrated solution from a more concentrated solution.

• Molarity

• Normality

• Dilution

• Molality

In dilution of solution,

• a solute is added to the solution.

• the amount of moles increases.

• solvent is added to the solution.

• volume of solution decreases.

Which compound is least soluble at 10°C?
