What is the difference between isosmotic and isotonic solutions?
Isosmotic solutions have the same concentration of solutes, while isotonic solutions have the same concentration of solutes and the same osmotic pressure.
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.
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 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.
What is the difference between Osmotic and Oncotic pressure?
Osmotic pressure is the pressure exerted by water moving across a semipermeable membrane due to differences in solute concentration. Oncotic pressure, also known as colloid osmotic pressure, is the osmotic pressure exerted by proteins in the blood plasma that helps to maintain fluid balance between the blood vessels and tissues.
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.
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 :-)
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 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.
What is the difference between isosmotic and isotonic solutions?
Isosmotic solutions have the same concentration of solutes, while isotonic solutions have the same concentration of solutes and the same osmotic pressure.
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 solutions will give rise to a greater osmotic pressure at equilibrium 3.60 g of nacl in 351.2 ml water or 50.0 g of glucose in 400.8 ml water for NaCl mw 58.5 amu for glucose m?
The greater osmotic pressure will be observed with 3.60 g of NaCl in 351.2 ml of water. This is because NaCl dissociates into two ions (Na+ and Cl-) in solution, contributing more particles that will contribute to osmotic pressure, compared to glucose which does not dissociate.
What has the author H N Morse written?
H. N. Morse has written: 'The osmotic pressure of aqueous solutions'
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 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.
Is a colligative property of solutions in which the pressure created by osmosis equals the pressure required to prevent osmosis?
Yes, the colligative property you are referring to is osmotic pressure. Osmotic pressure is the pressure required to prevent the flow of solvent across a semipermeable membrane. It is directly proportional to the concentration of solute particles in the solution.
