The water potential and osmotic potential of pure water are (a) 100 and 200 (b) zero and 100 (c) 100 and zero (d) zero and zero.
Option D Water potential or chemical potential in pure water is zero bar, arbitrarily. Osmotic potential or solute potential represents the effect of dissolved solutes on water potential solutes reduce the free energy of water by diluting the water. The osmotic potential of pure water is zero. If solutes are added to water its potential becomes less than that of pure waters is expressed as a negative value.
