What is the term for the pressure that develpes when two solutions of varying conceration are separated by a membrane?
Osmotic pressure... you must be in my nutrition class :-)
How does tonicity relate to osmosis?
Tonicity refers to the measure of the effective osmotic pressure gradient between two solutions. The higher the difference in the tonicity between the two solutions, the more osmosis transpires.
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 does the level of a more concentrated solution rise when two solutions of different concentrations are separated by a semipermeable membrane and when does it stop rising?
The more concentrated solution is hypertonic and osmotic pressure (a hydrostatic force whose sole purpose in life is to make concentrations equal) tends to move solvent into the more concentrated solution. It will stop rising when either a) the solution concentrations are the same on both sides of the membrane, or b) when the osmotic pressure becomes equal to the ambient air pressure.
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.
What two solutions are isotonic?
Two isotonic solutions are two solutions that have the same osmotic pressure. This term is generally used referring to solutions in a cell or body fluid.

How does tonicity relate to osmosis?
Tonicity refers to the measure of the effective osmotic pressure gradient between two solutions. The higher the difference in the tonicity between the two solutions, the more osmosis transpires.
What is isotonic pressure?
A term applied when two solutions have identical concentrations of of solute molecules and hence the same osmotic pressure, or isotonic pressure.
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.
How are osmosis and diarrhea related?
There are two major types of diarrhea: secretory and osmotic diarrhea. Osmotic diarrhea occurs when unabsorbable solutes in the stool osmotically pull water towards them through the wall of the gut, producing diarrhea.
What does hypertonic mean in science?
1. Pathology Having extreme muscular or arterial tension. 2. Chemistry Having the higher osmotic pressure of two solutions.
What is an isotonic supplement?
Isotonic is a term to compare two solutions. It describes a balance in the concentration of solutes, so that there is no osmotic pressure difference (i.e. water will not flow across the membrane). An isotonic supplement would be a term used to describe a supplement, that when dissolved in a specific amount of water, would be equal in concentration to the human body.
What is osmotic equilibrium?
Osmotic equilibrium refers to the state where there is no net movement of water across a semipermeable membrane due to an equal concentration of solute on both sides. This balance prevents further water flow and maintains stability in the system.
Is Hartman's solution hypertonic?
Yes . The balance of chemicals between the blood and Hartman's solutions is isotonic and therefore there is an equilibrium reached between the two solutions. this reason is why it is used for major blood loss.
What occurs when positive and negative electrical changes build up in the clouds?
Eventually the two charges will have to balance out with what we call lightening?
