  • What is another name for solubility in chemistry?
    Solubility is also called concentration or molarity.
  • How is molarity defined?
    Molarity is defined as moles of solute per liter of solution.
  • What does solubility indicate about a solution?
    Solubility indicates how much solute can dissolve in a solvent.
  • What happens when you add more solute than the solvent can dissolve?
    Any excess solute remains undissolved as a solid at the bottom of the container.
  • What is a saturated solution?
    A saturated solution contains the maximum amount of dissolved solute in the solvent.
  • What is an unsaturated solution?
    An unsaturated solution can still dissolve more solute beyond what is currently dissolved.
  • What is a supersaturated solution?
    A supersaturated solution contains more solute than the equilibrium concentration, achieved by applying heat.
  • How can you create a supersaturated solution?
    A supersaturated solution is created by applying heat to dissolve more solute than the normal maximum.
  • What happens to a supersaturated solution when heat is removed?
    When heat is removed, the excess solute recrystallizes and forms a precipitate.
  • Why are supersaturated solutions considered unstable?
    Supersaturated solutions are unstable because the excess solute can easily precipitate out when conditions change.
  • What term describes the process of excess solute forming a solid when heat is removed?
    This process is called recrystallization, resulting in a precipitate.
  • What is the relationship between solubility, concentration, and molarity?
    Solubility, concentration, and molarity all refer to how much solute is dissolved in a solution.
  • In a saturated solution, what happens if you add more solute?
    The added solute will not dissolve and will remain as a solid at the bottom.
  • How does temperature affect the solubility of a solute?
    Increasing temperature allows more solute to dissolve, creating a supersaturated solution.
  • What is the maximum amount of solute that can dissolve in a solvent called?
    It is called the solubility limit or equilibrium concentration.
