Question 1

What is the equilibrium of solubility?

Accepted Answer

The state in which the rate of dissolution of a solute is equal to the rate of precipitation of the solute

Answer

The state in which a solute fully dissolves in a solvent

Answer

The state in which the rate of dissolution of a solute is greater than the rate of precipitation of the solute

Answer

The state in which a solute does not dissolve in a solvent

Question 2

What is Ksp (solubility product constant)?

Accepted Answer

The product of the concentrations of the ions in a saturated solution of a compound

Answer

The equilibrium constant for a reaction in which a compound dissociates into its constituent ions

Answer

The ratio of the concentration of the solute to the concentration of the solvent in a solution

Answer

The sum of the concentrations of the ions in a saturated solution of a compound

Question 3

What is the common ion effect?

Accepted Answer

The decrease in the solubility of a slightly soluble compound when a common ion is added to the solution

Answer

The formation of a complex ion when a common ion is added to the solution

Answer

The increase in the solubility of a slightly soluble compound when a common ion is added to the solution

Answer

The complete precipitation of a compound when a common ion is added to the solution

Question 4

What is the purpose of calculating molar solubility?

Accepted Answer

To determine the maximum amount of solute that can dissolve in a solvent at a given temperature

Answer

To calculate the ratio of solute to solvent in a solution

Answer

To measure the rate of dissolution of a solute

Answer

To determine the total volume of a solution

Question 5

What is the effect of temperature on solubility?

Accepted Answer

Generally, an increase in temperature increases the solubility of solid solutes and decreases the solubility of gas solutes

Answer

An increase in temperature has no effect on the solubility of solutes

Answer

An increase in temperature decreases the solubility of solid solutes and increases the solubility of gas solutes

Answer

An increase in temperature increases the solubility of both solid and gas solutes

Question 6

What is meant by the term 'supersaturated solution'?

Accepted Answer

A solution that contains more dissolved solute than what would normally be possible at equilibrium

Answer

A solution that has a higher density than the solvent

Answer

A solution that has a lower temperature than the solvent

Answer

A solution that contains less dissolved solute than what would normally be possible at equilibrium
