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.

If the osmotic pressure is greater is the number of solute particles lower?
No, if the osmotic pressure is greater, it typically indicates that the number of solute particles is higher. Osmotic pressure is directly related to the concentration of solute particles in a solution; as the concentration increases, the osmotic pressure also increases. Therefore, a greater osmotic pressure suggests a higher number of solute particles in the solution.
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.
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.
Why is osmotic pressure a colligatic property?
Osmotic pressure is considered a colligative property because it depends on the number of solute particles in a solution rather than their identity. When a solute is dissolved in a solvent, it disrupts the equilibrium between the solvent molecules, leading to a net movement of solvent across a semipermeable membrane to dilute the solute. This effect is proportional to the concentration of solute particles, making osmotic pressure a function of solute quantity rather than chemical nature.
What colligative property best determine molecular mass of solute?
It is Osmotic Pressure..
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'
