hypertonic effect
A red blood cell, when placed in 50% NaCl solution, will shrink as the water contained in it will be sucked into the surrounding solution doe to the osmotic pressure difference.

600ml.
About 80ml of water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution.
Yes, during process of osmoses the solvent from higher concentration to lower concentration moves through semipermeable membrane, the 2% solution has lower concentration of solute therefore higher concentration of solvent.
0.9%
5% in pure water
because its osmotic presure is greater than of the cell
The solution of NaCl with the concentration 0,9 % is considered normal saline; the osmotic pressure is equal to the pressure in the cells.
12ml
Because the environment is Isotonic (having the same or equal osmotic pressure).
A red blood cell, when placed in 50% NaCl solution, will shrink as the water contained in it will be sucked into the surrounding solution doe to the osmotic pressure difference.
Colloids: is a term used to collectively refer to the large molecular weight (nominally MW > 30,000) particles present in a solution. In normal plasma, the plasma proteins are the major colloids present. As the colloids are solutes they contribute to the total osmotic pressure of the solution. This component due to the colloids is typically quite a small percent of the total osmotic pressure. It is referred to as COLLOID OSMOTIC PRESSURE (or sometimes as the ONCOTIC PRESSURE).
0.85% nacl sol or normal saline solution is used as it is an isotonic solution which will emmulsify bacterial cells and dont cause any injury ( injury due to osmotic gradient in which cell can shrink or swell/burst ). solution upto 0.98% can be used.
A pharmacist mixed a 20 percent solution with a 30 percent solution to obtain 100 liters of a 24 percent solution. How much of the 20 percent solution did the pharmacist use in the mixture (in liters).
