Detailed explanation-1: -The red blood cell will gain water, swell ad then burst. The bursting of the red blood cell is called hemolysis. If a red blood cell is placed in a solution that contains 0.85% NaCl the water moves equally out and into the cell, the solution in the cell and the solution around the cell are the same or in equilibrium.
Detailed explanation-2: -When a red blood cell is placed in a hypotonic solution, there will be a net movement of free water into the cell. This situation will result in an increased intracellular volume with a lower intracellular solute concentration. The solution will end up with a higher overall solute concentration.
Detailed explanation-3: -Due to the diffusion process which states that when a cell is placed in a concentrated solution, water moves from a high concentration of water (RBC) to a low concentration of water (saline water). Due to this a red blood solution loses water and shrinks in a concentrated saline solution.
Detailed explanation-4: -Answer and Explanation: Nothing happens to red blood cells in an isotonic solution as an isotonic solution has the same osmotic pressure as a red blood cell.
