If some solute is dissolved in pure water, its water potential _____________.
Open in App
Solution
The correct option is B Decreases
The water potential of a solution can be determined using pure water as the standard of reference. The pure water, at atmospheric pressure, has a water potential of zero(0). The addition of solute particles reduces the free energy of water and thus decreases the water potential(negative value). Because of this, the water potential of a solution is always less than zero.So, the correct answer is 'Decreases'
