Which of the following will favor the spontaneous formation of a solution?

An increase in the disorder of a system A decrease in the internal energy of a system

Which of the following is defined as having a relatively low concentration of solute

Dilute

Two clear liquids are poured into a container and immediately separate into layers. What can we conclude about these liquids?

The liquids must have very different polarities.

Solubility is determined by: solute-solute forces solvent-solvent forces solute-solvent forces all of the above

all of the above

Which of the following retains more carbonation (dissolved carbon dioxide)

chilled soda

A solution that contains a low concentration of solute is called

dilute

When a solution is saturated, more solute will typically dissolve if you

heat the vessel

A solution in which solute-solvent interactions are the same or similar to the solute-solute and solvent-solvent interactions is called a(n

ideal solution

The solubility of a gas in a liquid will typically decrease with

increasing temperature

Typically, the solubility of a solid in a liquid will increase with

increasing temperature

When two liquids have infinite mutual solubility, they are said to be

miscible

A student is making chocolate milk and mixes the chocolate powder (solute) into the milk (solvent) until no more powder can be dissolved. The mixture described is

saturated

When a carbonated beverage is sealed, it is

saturated with carbon dioxide

The maximum concentration that a solution can achieve with respect to a particular solute is called that solute's

solubility

Generally, if a saturated solution at a high temperature, is allowed to cool to room temperature, and doesn't recrystallize, it then becomes

supersaturated

If solute is added to a solution and it dissolves instead of falling to the bottom of the container, the original solution was

unsaturated

______________ do NOT form a solution

water and olive oil

How does the concentration of dissolved CO2 in the soda beverage change when the bottle is opened?

It decreases.

Which description best fits the definition of solubility?

Solubility is the extent to which a solute may be dissolved in a solvent.

Considering the steps involved in dissolution, which of the following do you expect to speed up a dissolution process? Select all that apply.

Stirring the solution vigorously Grinding the solute down into tiny particles Gently heating the solution

Which of the following terms describe a solution with a concentration of solute above that solute's solubility?

Supersaturated
