Osmotic pressure = i x M x R x T
i = van't Hoff factor
The van't Hoff factors are:
MgCl2 - i = 3 (Mg2+ and 2Cl-)
NaCl - i = 2 (Na+ and Cl-)
KBr - i = 2 (K+ and Br-)
Glucose - i = 1 (doesn't ionize)
MgCl2 has the greatest affect on osmotic pressure because it has the largest van't Hoff factor.

What is meant by Isotonic glucose solution solution?
An isotonic glucose solution is a solution that has the same concentration of glucose as body fluids, such as blood. This means that the solution will not cause water to move in or out of cells, helping to maintain the balance of fluids within the body. Isotonic glucose solutions are often used in medical settings to provide hydration and energy to patients.
Which plasma constituent is the main contributor to osmotic pressure?
Albumin is the main constituent in plasma that contributes to osmotic pressure. It helps maintain the balance of fluids between the blood and tissues by exerting osmotic pressure to keep fluid within the blood vessels.
What will happen to the cells of a patient who is provided with an intravenous solution that is isosmotic to intracellular fluids?
If the intravenous solution is isosmotic to intracellular fluids, there will be no net movement of water into or out of the cells since the osmotic pressure inside and outside the cells will be equal. The cells will remain in isotonic conditions, maintaining their normal shape and function without swelling or shrinking.
Which salt solution is more likely to be isotonic to the intracellular fluids of a potato?
A 0.9% sodium chloride solution (normal saline) is more likely to be isotonic to the intracellular fluids of a potato. This concentration is similar to the overall solute concentration inside the cells of a potato, making it the best choice to prevent osmotic imbalance when the potato is immersed in the solution.
What causes osmotic pressure to develop in a cell?
Osmotic pressure occurs when two solutions of different concentrations are separated by a semi-permeable membrane. Often the solute cannot move through the membrane, so there is pressure for the water to move from the less concentrated side to the more concentrated side, to dilute it.
Why would osmotic pressure be low in someone who is starving?
histamines.
What pressure is responsible for reabsorption and for pulling fluids into the venous end of capillaries?
Osmotic pressure
What is meant by Isotonic glucose solution solution?
An isotonic glucose solution is a solution that has the same concentration of glucose as body fluids, such as blood. This means that the solution will not cause water to move in or out of cells, helping to maintain the balance of fluids within the body. Isotonic glucose solutions are often used in medical settings to provide hydration and energy to patients.
What is crystalloid osmotic pressure?
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).
Which plasma constituent is the main contributor to osmotic pressure?
Albumin is the main constituent in plasma that contributes to osmotic pressure. It helps maintain the balance of fluids between the blood and tissues by exerting osmotic pressure to keep fluid within the blood vessels.
The thirst center in the hypothalamus is stimulated by what?
the osmotic pressure of body fluids, vascular volume and angiontensin
What is the definition of iso tonic solution?
An isotonic solution is a solution that has the same osmotic pressure as bodily fluids. This means that it has the same concentration of solutes as cells in the body, allowing for proper hydration and movement of water across cell membranes without causing cell shrinkage or swelling.
Explain in briefly Berkley and Hartley's method of osmotic pressure measurement and states its uses?
Berkley and Hartley's method of osmotic pressure measurement involves using a semipermeable membrane to separate a solution from its pure solvent. The difference in height between the two liquid levels in a U-shaped tube is used to measure the osmotic pressure of the solution. This method is commonly used to determine the molecular weight of unknown substances and can also be used in medical and biological research to study cell membranes and concentrations of substances in biological fluids.
What type of pressure causes to enter the venous side of the capillary?
The pressure in the tissue surrounding the capillary, called interstitial fluid pressure, causes fluids to enter the venous side of the capillary due to the pressure gradient. This pressure helps to balance the forces of filtration and reabsorption in the capillary beds.
What is the significance of osmotic pressure in biology?
Osmotic pressure is important in biology because it helps regulate the movement of water and nutrients in and out of cells. It plays a key role in maintaining the balance of fluids inside and outside of cells, which is essential for cell function and overall health.
What does warm water and salt after a tooth pulled?
Osmotic pressure draws fluids OUT, toward the salt solution. As long as you keep pulling any possible infection that way, you'll have less chance of problems. Osmotic pressure on an infectious bacteria also weakens the bacteria's ability to reproduce and spread the infection. Salt water is a low-tech, highly effective way to control infection in a tooth extraction.
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
