Understanding Solubility and Solubility Product

What happens to ionic compounds that are water-insoluble when they are placed in water?

• They turn into a liquid.

• They dissolve completely.

• They form a gas.

• They remain in the solid phase.

What does the solubility product (KSP) represent?

• The total mass of a compound.

• The rate of dissolution.

• The equilibrium constant for a slightly soluble compound.

• The boiling point of a solution.

In the solubility product expression, why are solids not included?

• Solids are always included.

• Solids are not part of the equilibrium.

• Solids do not dissolve.

• Solids have no concentration.

How is the solubility product expression for magnesium hydroxide written?

• KSP = [Mg^2+]^2[OH^-]^2

• KSP = [Mg^2+][OH^-]

• KSP = [Mg^2+]^2[OH^-]

• KSP = [Mg^2+][OH^-]^2

What is the relationship between the concentration of magnesium ions and hydroxide ions in magnesium hydroxide?

• Magnesium concentration is double that of hydroxide.

• They are equal.

• Hydroxide concentration is double that of magnesium.

• Hydroxide concentration is half of magnesium.

What is the molar solubility of copper 1 bromide if its KSP is 6.3 * 10^-9?

• 7.9 * 10^-5 moles per liter

• 6.3 * 10^-9 moles per liter

• 2.1 * 10^-4 moles per liter

• 1.3 * 10^-2 moles per liter

How do you calculate the molar solubility of a compound from its KSP?

• By adding the KSP to the ion concentrations.

• By solving the KSP expression for the ion concentrations.

• By dividing the KSP by the ion concentrations.

• By multiplying the KSP by the ion concentrations.

What is the KSP expression for calcium hydroxide?

• KSP = [Ca^2+][OH^-]

• KSP = [Ca^2+][OH^-]^2

• KSP = [Ca^2+]^2[OH^-]

• KSP = [Ca^2+]^2[OH^-]^2

If the KSP of silver chromate is 1.1 * 10^-12, what is the molar solubility?

• 6.5 * 10^-5 mol

• 2.1 * 10^-4 mol

• 1.1 * 10^-12 mol

• 3.7 * 10^-1 mol

What does the molar solubility of a compound indicate?

• The boiling point of the compound.

• The total mass of the compound.

• The number of moles of the compound that will dissolve per liter of water.

• The rate at which the compound dissolves.
