  • RTc

3. Which of these statements about the tonity of solution is incorrect?

  • There are only 2 different types if tonity
  • Isotonic solution (the solution has the same osmotic pressure compared in the cell)
  • Hypertonic solution (the solution has higher osmotic pressure compared in cell)

4. Which of these do not affect equilibrium?
