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.
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.
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
Normal saline solution (0.9% NaCl) is isotonic to cells, so it would have minimal impact on the cells of Rhoeo discolor. It would help maintain the cells' normal volume and osmotic balance without causing them to shrink or swell. Overall, the cells would not be significantly affected by exposure to normal saline solution.
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)
Water is considered hypotonic because it has a lower solute concentration compared to the cytoplasm of most cells. When a cell is placed in a hypotonic solution like water, water molecules will move into the cell in an attempt to equalize solute concentrations, potentially causing the cell to swell or burst.
The Tyndall effect is the scattering of light by particles in a colloid or fine suspension, making the beam of light visible. In a sugar solution, which is a true solution (not a colloid), the particles are too small to scatter light significantly, so the Tyndall effect is not observed.
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.
Molality is independent of temperature, so when you are trying to find changes in boiling and freezing points you need something that will stay constant regardless of the change in temperature. Molarity is temperature dependent and also is based on the volume of a solution, both of which are needed to calculate pressure using the ideal gas law, PV=nRT. Osmotic pressure is similar but we substitute the number of moles of the solution and the volume by using the molarity, you cannot do this with molality, since it is dependent on mass, not volume.
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
Using an isotonic solution helps to prevent osmotic changes in the specimen, which could cause it to shrink or swell. This ensures that the specimen remains in its natural state, allowing for accurate observation and minimal distortion under the microscope.
Dehydrates the yeast cells be creating an osmotic imbalance so the yeast cell crenates and dies. therefore the yeast cell activity is reduced.
The Nattharick's solution does not cause lysis of white blood cells because it is an isotonic solution, meaning it has the same osmotic pressure as the cells. This balance in osmotic pressure prevents the solution from causing the white blood cells to take up too much water or lose too much water, which would result in cell lysis.
