Q30 / 200 · NEET 2022 (Phase 1) · Botany

Addition of more solutes in a given solution will:

  • Correct answer
    A
    lower its water potential
  • B
    make its water potential zero
  • C
    not affect the water potential at all
  • D
    raise its water potential

Solution

Water potential is the measurement of chemical potential of water. The pure water has zero water potential. This is measured with the help of solute potential, pressure potential, and matric potential.

The greater the concentration of water in a system, the greater is its water potential. If more solute is dissolved in water, the solution has less free water molecules and hence the water potential is decreased.

Hence, the correct answer is option: 'A'.
