If a blood cell is put into a high sodium solution it will become crenated (shrivel up). Water will flow out of the cell into the solution.
If it is put in a low sodium solution it will absorb water/expand outward.
If the sodium concentration of the blood cell and outside environment are the same, nothing will happen.
shrivel
The red blood cell will become turgid because water will move from the glucose solution to the red blood cell.
It shrinks as water moves out of the cell.
A 2 percent solution of sodium chloride is considered isotonic to red blood cells, meaning it will not cause crenation (shriveling) or hemolysis (bursting). Isotonic solutions have the same osmotic pressure as red blood cells, allowing for equilibrium and maintaining cell integrity.
Solid sodium forms. Sodium is reduced.
In isotonic solution nothing ail happen. In hypertonic solution fluid will leave the cell to dilute the external fluid, causing the cell to crenate. In Hypotonic solution fluid will move into the cell to dilute the contents of the cell, causing it to bust or haemolyse.
Hypotonic Solution
When a red blood cell is exposed to an isotonic solution, there is no net movement of water into or out of the cell. This means that the cell maintains its normal shape and volume, as the concentration of solutes inside and outside the cell is balanced.
This is not true. An isotonic solution is one that is equivalent in concentration to that found within human plasma so that is usually desirable. On the other hand, a person may have too little of an ion. In that case the amount needs to be replaced using a hypertonic solution. The trouble with that is that if the patient is not carefully monitored, too much of whatever ion is used will enter the cells, causing the cells to draw more water in to maintain balance. When that happens, especially with sodium, the patient must be monitored closely because giving too much can cause the sodium level in the cells to exceed normal levels. When that happens, the cells draw more water in which can cause the cells to swell and then the membranes to begin to leak such as we see with pulmonary edema.
Provided the concentration of salt is higher than the salt concentration in the red blood cell, the red blood cell, through the process of osmosis and the principal of diffusion, will shrink, as water flows from within the red blood cell to the solution.
Hypertonic solution is the solution which contain more solute in it as compare to the cell internal solution now as the law of diffusion the solvent moves from low concentration of solute to high conc of solute so the solvent move out from the cell to the solution and cell ultimately will shrink
The cell explodes!
