The osmotic effect of a solution is its ability to change the flow of water from itself to another solution that it can access. For instance, if you are injecting a high-osmotic solution directly into the blood stream, you can cause the patient to become dehydrated because the solution will pull the water from the patient's body tissues into the blood stream until it is equalized between the body tissues' osmotic force and the solution's osmotic force.
In contrast, if you inject a solution that is too dilute, you can cause cells to rupture as the water from the dilute solution filters into the cells to try to equalize the osmotic forces between the cell's interiors and the solution.

What is the role of NaCl in Nutrient broth?
NaCl is generally added to the nutrient media for maintaining the Osmotic pressure. Maintaining osmotic pressure is important, because, increase or decrease in the osmotic pressure leads to cell burst or death due to the effect of osmosis. So, maintaining the osmotic pressure is done by adding correct amount of NaCl.
Is water isotonic hypotonic or hypertonic?
Hypertonic solution is one which has higher osmotic concentration and less solvent concentration as compared to another solution. Hypotonic solution is one that possesses lower osmotic concentration and higher solvent concentration as compared to another solution. Isotonic solution is a solution that has same concentration, osmotic as well as solvent, as that of another solution . Pure water is hypotonic but water having salt is isotonic. So,water may be either isotonic or hypotonic
How does a syrup acts as a self preservative?
Syrups contain up to 85% sucrose in water. Since the solution is so saturated it has a high osmotic pressure and thus no free water available for microbial growth
When does osmotic equilibrium occur?
When the water potential gradient evens out, so that the water potential on eithersides of the partially permeable membrane is equal. Also, when something is placed in an isotonic solution ( a solution with the same waterpotential as the organism contains)
Is osmotic a diuretic?
Osmotic diuretics are a type of diuretic not a specific drug. Osmotic diuretics work by increasing blood flow to the kidneys and preventing the tubes in the kidneys from making such concentrated urine so that there is no gradient for water to be reabsorbed so you will pee all that water out. An example of an osmotic diuretic is mannitol.
What solution has the same salt concentration as blood and is used for transfussion?
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
What determines the osmotic pressure of any given solution?
Osmotic pressure of saline (0.91% NaCl w/v) is arround 0.0085 ATM.The osmotic pressure is 7.58 ATM at 25 °C. P=MRT The molarity of 0.9% NaCl is 0.155M. But it has 2 ions per formula so 0.31 mol/L * 0.082 latm/Kmol * 298K= 7.58 ATM
What solution will cause hemolysis?
Hemolysis is the bursting of red blood cells (hemo- blood and lysis- bursting). There are three types of solutions that blood can be put into: hypertonic, hypotonic and isotonic. The names of these give you some clue as to how the cell will behave in solution. Hypertonic solutions have greater osmotic pressure than the cells they contain, which will cause the cell to shrivel as its contents diffuse into the solution. Hypotonic solutions have less osmotic pressure than the cells inside of them, so the contents of solution will diffuse across the cell membrane and into the cell, eventually causing it to swell and burst (hemolysis). Isotonic solutions have osmotic pressure equal to that of the solutes they contain, so no net change is observed.
Does a emulsion show the Tyndall effect?
yes.because when we are vigorous shaking the solution of two dissimilar liquids it it ii mix for 1 or 2 seconds .let it be the solution for 1 or 2 minutes it ll show the Tyndall effect ...so we can observe Tyndall effect in an emulsion solution .
Effect of sodium chloride on yeast activity?
Dehydrates the yeast cells be creating an osmotic imbalance so the yeast cell crenates and dies. therefore the yeast cell activity is reduced.
Can a solution be isosmotic but not isotonic?
Reasons and explanation -Isotonic solutions contain only non-penetrating solutesand have the same osmotic pressure as the cells they surround. They are neither absorbed nor do they absorb anything from the surrounding cell. They have the same concentration of salt as the blood and human cells in the body.whereasIsosmotic solutions contain both penetrating and non-penetrating solutes. They have the same osmotic pressure of the surrounding cells. Penetrating solutes are solutes that can pass through the membrane of the cell and increase the osmotic pressure in the cell. This forces the cell to absorb more water to equalize the difference in pressure. This may lead to bursting of the cell when too much water is absorbed.
