Why does salt produce the a greater change in osmotic pressure than sugar?

The osmotic pressure depends on the number of dissolved particles in solution. When you dissolve one mole of sugar molecules, the result is one mole of dissolved particles. When you dissolve sugar, or sodium chloride (NaCl), the salt breaks apart into two ions, Na+ and Cl-. So when you dissolve one mole of salt, you have two moles of particles in solution. If you used something like magnesium chloride, MgCl2, you'd get 3 moles of particles for each mole of MgCl2 -- one mole of Mg2+ and 2 moles of Cl-.

How osmotic pressure helps in translocation?
Translocation is caused due to the change in the osmotic pressure in the upper and lower part of a tree/plant.when there is a difference of water content in the upper part and the lower part then the water will move towards the upper region where endosmosis has taken place. this translocation takes place with the help of sieve tubes.
What is osmotic change?
osmosis establishes or maintains the stable state of equillibrium
How does the water pressure change at each level in a jug?
As you go deeper into a jug, there is more water on top of you, pressing down. Because of this, the deeper you are, the greater the water pressure becomes.
What is the tonicity of a bacterial cell?
Isotonic conditions will not change the cell in bacterial or an human cell. Because the water concentration in the cell equal.Hypotonic conditions will increase the solute in the cell because of the osmotic pressure inside the cell. Cell may burst if to much solute is inside the cell. Bacterial and human cell.Hypertonic conditions is said to have osmotic pressure. Because the concentration in the environment has an higher concentration than inside the cell so all the solute will drive out of the cell and cause it to dry out.
Differentiate between a hypo- and a hyperreactor relative to the cold pressor test?
A cold pressor test is used to determine if there is a change is blood pressure when a subject is exposed to a cold stimulus. If the subject has a 22 mm/Hg or less change in blood pressure, they are considered a hyporeactor. If the subject has a 23mm/Hg or greater change in blood pressure, they are considered a hyperreactor.
What is osmotic rate?
the change of osmotic pressure over time
How do net hydrostatic pressure and net osmotic pressure each change along the length of a capillary?
Net osmotic pressure stays about the same and net hydrostatic pressure decreases.
Why is sterile water not ideal when preparing a dilution series?
Because it will change the osmotic pressure .
What causes the speed of a tornado?
Most winds on earth are produced by pressure differences. The greater the pressure change over a given distance, the greater the wind speed. Tornadoes produce a large pressure drop over a very short distance, resulting in extremely high winds.
What is a pressure gradient and how is it related to air movement?
Pressure gradient is the rate of pressure change as you change position, not just the difference between the lowest pressure and the highest pressure, but how great (or small) the physical distance between them. Since it the pressure difference that make air flow (wind) the greater the pressure gradient, the greater the wind.

How does pressure change as you go from the surface toward the center if the earth?
The pressure increases as you go deeper. The deeper you go the greater the pressure
How does pressure change as you go from the surface toward the center if earth?
The pressure increases as you go deeper. The deeper you go the greater the pressure
Which gas experiences a greater change in solubility per unit pressure?
boobies
Why does the pressure over continents change with the seasons?
The air pressure over the continent may be heavy or less. The changes in temperature only produce pressure and the temperature change with seasons.
Why does fluid Pressure change with the elevation and depth?
At a greater depth, the weight of all the liquid (or gas) above adds to the pressure.
When materials pass into and out of a cell at equal rates there is no net change in concentration inside the cell. the cell is in a state of?
The cell is in a state of equilibrium. Meaning it is in an isotonic solution and there is no net osmotic pressure on the membrane.
