Chemistry II Unit 7 Review

Front

What is a supersaturated solution?

Back

A supersaturated solution is a solution that contains more solute than it can theoretically hold at a given temperature, resulting in excess solute that can precipitate out.

Front

What is the role of the anode in a Galvanic Cell?

Back

In a Galvanic Cell, the anode is the negative electrode where oxidation occurs, and electrons are released.

Front

What is an unsaturated solution?

Back

An unsaturated solution is a solution that contains less solute than it can dissolve at a given temperature.

Front

What is the solubility of KNO3 in water at 40°C?

Back

At 40°C, the solubility of KNO3 is approximately 63 grams per 100 grams of water.

Front

How do you calculate Ksp from solubility?

Back

Ksp can be calculated using the formula Ksp = [Ag+]^3[PO4^3-], where [Ag+] is the molarity of silver ions and [PO4^3-] is the molarity of phosphate ions.

Front

What is the definition of Ksp?

Back

Ksp, or solubility product constant, is the equilibrium constant for a solid substance dissolving in an aqueous solution.

Front

What happens in a saturated solution?

Back

In a saturated solution, the maximum amount of solute has been dissolved at a given temperature, and any additional solute will not dissolve.

Front

What is the significance of temperature in solubility?

Back

Temperature affects solubility; generally, solubility of solids increases with temperature, while the solubility of gases decreases.

Front

What is the difference between a saturated and unsaturated solution?

Back

A saturated solution contains the maximum amount of solute that can dissolve, while an unsaturated solution contains less solute than can be dissolved.

Front

What is the formula for calculating molarity?

Back

Molarity (M) = moles of solute / liters of solution.
