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.
How does osmotic potential affect diffusion?
Osmotic potential influences the movement of water molecules across a semi-permeable membrane. When there is a difference in osmotic potential between two solutions separated by a membrane, water will move from the area of lower solute concentration (higher water potential) to the area of higher solute concentration (lower water potential) to balance the concentrations. This affects the rate and direction of diffusion of solutes in and out of cells.
How does the addition of solutes affect water potential?
The addition of solutes decreases the water potential of a solution. This is because the presence of solutes reduces the free water molecules available to participate in osmotic processes, resulting in a lower overall potential for water movement.
Which of the following solutions has the highest osmotic pressure?
The solution with the highest concentration of solute particles will have the highest osmotic pressure.
What do we call 2 solutions that have the same water potential?
Iso-osmotic or isosmotic
How do you calculate solute potential?
ability of a medium to attract water molecules is known as osmotic potential. you may also label it as osmotic potential. at a time a system has more water potential and low solute potential and vice versa.

The solution with the highest concentration of solute particles will have the highest osmotic pressure.
The movement of the water across a membrane is termed?
The term used is osmosis. the direction of movement across the membrane is dependent on the concentration of solutes (known as the solute potential) which directly effects the osmotic potential.
What do we call 2 solutions that have the same water potential?
Iso-osmotic or isosmotic
How would a fluid with a high solute concentration affect osmotic pressure when compared to water?
A fluid with a high solute concentration would have a higher osmotic pressure compared to water. This is because the presence of more solute particles in the solution increases the pulling force required to prevent water from moving across a semipermeable membrane, leading to a higher osmotic pressure.
What colligative property best determine molecular mass of solute?
It is Osmotic Pressure..
How solute potential and water potential effect the rate of osmosis?
Solute potential and water potential both influence the rate of osmosis. A lower solute potential increases water potential, prompting water to move into an area with higher solute concentration. This increases the rate of osmosis. Conversely, a higher solute potential decreases water potential, causing water to move out of a region with lower solute concentration, slowing down the rate of osmosis.
Explain the relationship between solute concentration and osmotic pressure?
I believe the answer is this: The greater the solute concentration, the lower the water concentration. My source of information comes from 'Integrate; the Benjamin Cummings Custom Laboratory program for anatomy & physiology'
What is the source of energy for osmosis?
The source of energy for osmosis is the potential energy stored in the concentration gradient of the solute particles across a semipermeable membrane. This concentration gradient creates a driving force that leads to the movement of water molecules from an area of low solute concentration to an area of high solute concentration, resulting in osmotic flow.
