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-.See the Web Links for more information.
How calculate osmotic active ions?
To calculate osmotic active ions, you need to determine the concentration of solutes in a solution that contribute to osmotic pressure. This is typically done using the formula: Osmotic Pressure (π) = iCRT, where "i" is the van 't Hoff factor (number of particles the solute dissociates into), "C" is the molar concentration of the solute, "R" is the ideal gas constant, and "T" is the temperature in Kelvin. By identifying the ions present and their concentrations, you can compute the total osmotic pressure and thus the contribution of each ion to the overall osmotic activity.
Colligative properties are physical or chemical properties?
Purely physical: depends on the number of particles rather than on the kind of them.The number influences e.g. the boiling point elevation (decreased volatility), osmotic pressure (increased osmolality), etc.
Is it true or false a colligative property is a physical property affected by the type of the particles not the number of particles?
False. Colligative properties are physical properties of a solution that depend on the number of solute particles present, not the type of particles. Examples include boiling point elevation, freezing point depression, and osmotic pressure.
What happens to the temperature increase the number of particles what happens to the pressure?
Increasing the temperature the number of particles remain constant and the pressure increase.
Does concentration of plasma sodium ions affect the blood osmotic pressure?
yes, the higher number of plasma sodium ions the greater the osmotic pressure.
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 principle of osmometry?
Osmometry is a technique used to measure the osmotic pressure of a solution. It is based on the principle that the number of particles in a solution contributes to its osmotic pressure, which can be used to calculate the molecular weight of unknown solutes.

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.

How does reducing the volume of a gas affect its pressure if the temperature of a gas and the number of particles are constant?
At a constant temperature, the volume and the pressure are inversely proportional, that it, the greater the volume, the lesser the pressure on the gas, and viceversa.
Is it true or false a colligative property is a physical property affected by the type of the particles not the number of particles?
False. Colligative properties are physical properties of a solution that depend on the number of solute particles present, not the type of particles. Examples include boiling point elevation, freezing point depression, and osmotic pressure.

What happens to the temperature increase the number of particles what happens to the pressure?
Increasing the temperature the number of particles remain constant and the pressure increase.
How are pressure and the number of the particle related?
PV = NkT P: pressure V: volume N: number of particles in gas k: Boltzmann's constant T: absolute temperature More particles in a constant volume, constant temperature space means more pressure.
