What will be the direction of movement of water, when a solution A having water potential of – 9 bars and another solution of B of -4 bars is separated by a semipermeable membrane?
Options
(a) B to A
(b) In both A and B directions
(c) A to B
(d) only B directions
Correct Answer:
B to A
Explanation:
The direction of water movement is always from higher wate potential to lower water potential i.e. in energetically downhill direction, the direction of water in this case will be from -4 bars to -9 bars or from solution B to solution A through the semipermeable membrane.
