Quiz: Solutions & Solubility

A solution that contains the maximum amount of solute it can theoretically dissolve at a given temperature is considered...

• diluted.

• saturated.

• supersaturated.

• unsaturated.

The amount of solute that can be dissolved in a specific amount of solvent at a given temperature is its _________.

(hint: Table G provides these values as they change based on temperature)

• concentration.

• density.

• dilution.

• solubility.

A solution that is able to dissolve additional solute is described as

• supersaturated.

• concentrated.

• saturated

• unsaturated.

According to Table F, which cations in combination with chloride anions, Cl^-, would form an insoluble salt?

(hint: chloride ions are part of the halide group)

• K⁺

• Ca²⁺

• Pb²⁺

• Na⁺

According to Reference Table F, which compound is most soluble in water?

(hint: three of these will be considered insoluble by Table F.)

• ZnCO₃

• ZnSO₄

• BaSO₄

• BaCO₃

70 grams of KNO₃ are mixed into 100 grams of 40˚C water.

How would you categorize this solution? (Use Table G)

(hint: the water temperature is the x and the grams of solute is the y that form an x,y point on this chart. Then analyze how that point compares to the solubility curve of the solute)

• supersaturated

• saturated

• unsaturated

At 60˚C, which of these substances is the most soluble in 100. g of water?

• KNO₃

• NaCl

• NH₃

• HCl

The _________ is the part of the solution that was dissolved.

• solute

• solvent

• molarity

If 50.0 g of NaCl are dissolved into 500. g of water, what is the mass percent of NaCl ?

• 10.0 %

• 11.1 %

• 90.0 %

• 9.09 %

What is the van't Hoff factor of KBr?

(a.k.a. how many particles does each unit of KBr dissociate into when it dissolves?)

• 1

• 2

• 3
