Questions and Answers

Why do polar solutes dissolve in polar solvents?

  • Because they repel each other
  • Because they have opposite intermolecular interactions
  • Because they have no intermolecular interactions
  • Because they have similar intermolecular interactions (correct)
  • What is the process known as when some solute particles in solution collide with the solid solute particles and get separated out of solution?

  • Crystallisation (correct)
  • Condensation
  • Dissolution
  • Evaporation
  • What is solubility?

  • The separation of solute particles from the solution
  • The process of dissolution
  • The maximum amount of solute that can be dissolved in a specific amount of solvent at a specified temperature (correct)
  • The concentration of solute in a solution
  • Under what conditions does a state of dynamic equilibrium occur?
