Exploring the Solubility Product Constant

Which of the following ionic compounds is always soluble in water according to AP guidelines?

• Lead sulfate

• Calcium carbonate

• Potassium nitrate

• Silver chloride

What does it mean when an ionic compound is described as 'insoluble' in water?

• It forms a strong electrolyte.

• It does not dissolve at all.

• It dissolves completely.

• It exists at equilibrium with its ions.

What does the solubility product constant (Ksp) represent?

• The amount of solute that can be dissolved in a given amount of solvent.

• The rate at which a solute dissolves in a solvent.

• The equilibrium constant for the dissolution of an ionic solid.

• The concentration of a solute in a solution.

How does the value of Ksp relate to the solubility of a compound?

• A smaller Ksp indicates higher solubility.

• A larger Ksp indicates lower solubility.

• A larger Ksp indicates higher solubility.

• Ksp does not affect solubility.

In the example of barium sulfate, what happens if more barium ions are added to the solution?

• The equilibrium shifts to the left, precipitating out solid barium sulfate.

• More barium sulfate dissolves.

• The solution becomes unsaturated.

• The equilibrium shifts to the right, dissolving more barium sulfate.

What is the relationship between solubility and Ksp?

• Solubility is the product of the concentrations of the ions raised to their coefficients.

• Solubility is the amount of substance that dissolves to form a saturated solution.
