Hypotonic solutions have a lower solute concentration than the cell, causing water to move into the cell. In hypertonic solutions, the solute concentration is higher outside the cell, leading to water moving out of the cell. Isotonic solutions have equal solute concentration inside and outside the cell, resulting in no net movement of water.

Why different solutions of different substance at the same temperature have same osmotic pressure?
Osmotic pressure depends only on the concentration of the solute particles in a solution, not the type of solute. Different substances at the same concentration will exert the same osmotic pressure because the number of solute particles per unit volume is what matters in determining osmotic pressure, not the identity of the particles.
What do we call 2 solutions that have the same water potential?
Iso-osmotic or isosmotic
What pressure results from osmosis?
Osmotic pressure is the pressure that develops when water moves across a semi-permeable membrane to achieve equilibrium in solute concentrations between two solutions. It is dependent on the concentration of solute particles in the solution and temperature.
What are the properties do solutions have?
Solutions are homogeneous mixtures composed of a solute dissolved in a solvent. They are stable, have uniform composition throughout, and can vary in concentration. Solutions can exhibit properties unique to the solute-solvent interaction, such as boiling point elevation, freezing point depression, and osmotic pressure.
What is the ability of a solution to do work by osmosis?
The ability of a solution to do work by osmosis is determined by its osmotic pressure, which is the pressure needed to stop the flow of solvent into the solution through a semipermeable membrane. Solutions with higher osmotic pressure can exert more force and do more work through osmosis.
Solutions that have the same osmotic pressure are called .?
Solutions having the same osmotic pressures are called isotonic solutions
How do you determine Iso-osmotic concentration?
Iso-osmotic concentration refers to a solution that has the same osmotic pressure as another solution. To determine iso-osmotic concentration, you can use colligative properties such as freezing point depression or osmotic pressure measurements. By comparing these values between solutions, you can identify when two solutions have equal osmotic pressure and thus have iso-osmotic concentration.
Why different solutions of different substance at the same temperature have same osmotic pressure?
Osmotic pressure depends only on the concentration of the solute particles in a solution, not the type of solute. Different substances at the same concentration will exert the same osmotic pressure because the number of solute particles per unit volume is what matters in determining osmotic pressure, not the identity of the particles.
What do we call 2 solutions that have the same water potential?
Iso-osmotic or isosmotic
What is the term for the pressure that develpes when two solutions of varying conceration are separated by a membrane?
The term for this pressure is osmotic pressure. It occurs when there is a difference in solute concentration between two solutions separated by a semipermeable membrane.
What is isomotic solution?
iso-osmotic is different to isotonic even though they have the same number of solute particles as in the inside of red blood cells in isotonic solutions movement of water in and out of the cell is the same and RBC's remain unchaged, in iso-osmotic solutions RBC swell and burst this is because the semi permeable cell membrane cannot exclude iso-osmotic solutios as it can other solutes, causing a concentration gradient
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.
Is Vinegar an Isotonic solution?
No, vinegar is not an isotonic solution. Vinegar is an acetic acid solution, which means it has a different osmotic pressure compared to isotonic solutions.
Why tonicity is important?
because it refers to the effect of the solutions osmotic pressure has on water movement across the cell membrane of cells with in the solution. because it refers to the effect of the solutions osmotic pressure has on water movement across the cell membrane of cells with in the solution.
What has the author H N Morse written?
H. N. Morse has written: 'The osmotic pressure of aqueous solutions'
What is the importance of isotonicity in pharmacy?
The importance of isotonicity in pharmacy is to ensure solutions do not damage tissue or produce pain when administered. Osmotic pressure is governed by the number of particles of solute in a solution. Solutions with a higher osmotic pressure cause swelling of tissues as water passes from the administration site into the tissues or blood cells.
