Chemistry-Solubility
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
