Solubility and Solutions Video

What is solubility?

• The ability of a substance to melt

• The ability of a substance to freeze

• The ability of a substance to dissolve in water

• The ability of a substance to evaporate

Which salt is more soluble in water at the same temperature?

• Both are equally soluble

• Neither is soluble

• Copper II sulfate

• Potassium sulfate

What generally happens to solubility as temperature increases?

• It decreases

• It stays the same

• It increases

• It disappears

How can you find the solubility of a salt at a specific temperature using a solubility curve?

• By using a thermometer

• By measuring the salt directly

• By guessing

• By drawing lines on the graph

What is a supersaturated solution?

• A solution with less solute than it can hold

• A solution that is frozen

• A solution with no solute

• A solution with more solute than it can normally hold

A substance that cannot be dissolved into a solution is called

• soluble

• insoluble

What happens to the particles during the dissolving process?

• They become larger

• They mix together physically

How can you tell if a solution is concentrated?
