Exploring Solubility Product Constant Ksp

Which ion is NOT listed as highly soluble?

• Carbonate

• Ammonium

• Potassium

• Sodium

What is the role of ion-dipole attractions in solubility?

• They have no effect on solubility.

• They decrease solubility.

• They increase solubility.

• They only affect gases.

Which of the following ions is always considered highly soluble in water?

• Sulfate

• Nitrate

• Chloride

• Phosphate

What happens when a solution reaches saturation?

• The solid dissolves completely.

• No more solute can dissolve.

• The solution becomes less concentrated.

• The rate of dissolution decreases.

What happens at equilibrium in a saturated solution?

• The rate of dissolution exceeds recrystallization.

• The rate of recrystallization exceeds dissolution.

• The rates of dissolution and recrystallization are equal.

• No more solute can be added.

What does a larger KSP value indicate?

• Decreased ion concentration

• Higher solubility

• No change in solubility

• Lower solubility

What is the significance of the solubility product constant (KSP)?

• It indicates the solubility of a salt in water.

• It determines the pH of the solution.

• It predicts the temperature of dissolution.

• It measures the rate of recrystallization.

Can you compare the solubility of salts with different dissociation stoichiometries using KSP?

• Only if they dissociate into the same number of ions

• No, never

• Only if they are both insoluble

• Yes, always

What does molar solubility measure?

• The weight of solute dissolved at equilibrium.

• The volume of solvent needed to dissolve a solute.

• The concentration of ions in a saturated solution.

• The number of moles of solute that can dissolve in a liter of solution.

How can you determine the molar solubility of a salt?

• Using only the concentration of reactants.

• By comparing it to a standard solubility chart.

• Through direct measurement of the dissolved salt.

• By using the KSP and a balanced dissolution equation.
