When giving an iso-osmotic transfusion you do not want a solution that has the same salt concentration as blood but rather has the same tonicity(osmotic pressure). This is crucial because if the tonicity of blood changes it can cause cells to burst or shrink depending on the direction of change of the tonicity. So in the case of iso-osmotic transfusion you would give a 0.9% solution of NaCl. To prove that this is iso-osmotic to blood(close to 300 mosm) look below: 0.9% means 0.9gNaCl/100ml= 9gNaCl/L=(9gNaCl/L)*(1mole/58.5g)= 0.153moles/L Osmolarity = molarity*(number of ions)=0.153Molar*2= 0.306 osm = 306 mosm Hope that helps
A water solution that has the same salt concentration as the cells is said to be is isotonic.
This depends on salt concentration; however it ranges roughly from 1.0 (low) to 1.6 g/mL at high concentration. Seawater 1.02 - 1.03
Salt does not boil away at approx. 100 Celsius. The water evaporates causing the concentration of salt to increase.
You are probably looking for "dilute" but that is wrong, dilute is relative. A dilute solution of table salt (sodium chloride) can be a very different concentration to a dilute solution of slaked lime (calcium hydroxide).
Osmosis is the water solution. It is the same as salt concentration.
A hypotonic solution is a solution with a lower salt concentration than in normal cells of the body and the blood.
A hypertonic solution is a solution that has a high concentration of solute, in this case the solute being salt. When a red blood cell is placed in a hypertonic solution, since the salt concentration is higher in the outside of the cell, the water concentration is lower there as well. Therefore, through the process of osmosis, the water diffuses from the inside of the cell to the outside of the cell.
The concentration of sodium in blood plasma is 136-145 mmol/L.
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
It's a hypotonic solution. ex; blood, tears.
It is called an isotonic solution. If the salt concentration is higher, it is called hypertonic and if lower it is called hypotonic.
Iso means same, therefore the salt solution concentration is the same as the concentration of salt within the blood cells. So nothing happens - the RBC's remain the same (no shrinking/crenating or swelling/lysing)
The concentration of the salt solution does NOT change- it is saturated.
The greater the concentration of salt in an aqueous solution, the higher the electrical conductivity. This is because, with a greater salt concentration, there are more ions available to serve as a path for electron transfer in the solution.

It shrinks as water moves out of the cell.
