Which of the following statements is not true of osmotic process?
Answer Details
The statement that is not true of osmotic process is "The two solutions are of equal concentration at the beginning of experiment." Osmosis is the movement of water molecules across a selectively permeable membrane from an area of high concentration to an area of low concentration. For osmosis to occur, there must be a concentration gradient between the two solutions, which means that they must be of different concentrations initially. The process involves only the movement of water molecules and equilibrium is reached when there is equal distribution of water molecules. Therefore, is not true of osmotic process.
