What is formed when a solute is dissolved in a solvent?

• A solution

• A mixture

• A compound

• A precipitate

What is the difference between a concentrated solution and a dilute solution?

• The color

• The temperature

• The amount of solvent

What is a soluble solid?

• A solid that dissolves in water

• A solid that does not dissolve in water

• A solid that is heavier than water

• A solid that is lighter than water

What is an insoluble solid?

• A solid that dissolves in water

• A solid that does not dissolve in water

• A solid that is heavier than water

• A solid that is lighter than water

What happens when you keep adding a soluble solid to a beaker of water until no more will dissolve?

• You form a saturated solution

• You form a supersaturated solution

• You form a precipitate

• You form a mixture

What is the term used to compare the amount of a solute that can dissolve in a given amount of solvent?

• Concentration

• Solubility

• Saturation

• Dilutability

What is the effect of temperature on the solubility of most solutes?

• Solubility increases with temperature

• Solubility decreases with temperature

• Solubility remains constant with temperature

• Solubility is not affected by temperature

What happens to the particles of a solute when the temperature increases?

• They become smaller

• They become larger

• They vibrate and move more

• They stop moving

Choose the correct statements about the relationship between temperature and solubility: (a)  

​ (b)  

• As temperature increases, solubility increases.
• As temperature decreases, solubility increases
• Higher temperatures always reduce solubility
• Solubility is dependent of temperature changes
