What do you mean by osmotic dehydration?
Osmotic dehydration is the phenomenon of removal of water from lower concentration of solute to higher concentration through semi permeable membrane results in the equilibrium condition in both sides of membrane (Tiwari 2005).
What is osmotic pretreatment?
Osmotic pretreatment is used to reduce the initial water content, shortening total processing and air- drying time, and decreasing energy consumption (Ruiz-López et al., 2010).
What affects osmotic pressure?
Osmotic pressure is the pressure caused by water at different concentrations due to the dilution of water by dissolved molecules (solute), notably salts and nutrients.
What influences osmotic pressure?
Osmotic pressure is influenced by the concentration of solutes in a solution. It is directly proportional to the number of solute atoms or molecules and not dependent on the size of the solute molecules.
What is an example of osmotic pressure?
An example of osmotic pressure is the process to filter water. (physics) The hydrostatic pressure exerted by a solution across a semipermeable membrane from a pure solvent; the pressure needed to counteract osmosis.
Why is osmotic pressure important?
Osmotic pressure is of vital importance in biology as the cell’s membrane is selective toward many of the solutes found in living organisms. When a cell is placed in a hypertonic solution, water actually flows out of the cell into the surrounding solution thereby causing the cells to shrink and lose its turgidity.
What happens when osmotic pressure and temperature are same?
Question: When osmotic pressure and temperature are the same then: a) equal volume of solutions would contain equal number of moles of the solute.
How is osmotic pressure directly proportional to temperature?
Osmotic pressure is directly proportional to the concentration of solute. It is inversely proportional to the volume. It is directly proportional to temperature. It is directly proportional to the number of particles in the solution.
What happens to osmotic pressure as temperature increases?
Osmosis is the diffusion of solvent molecules into a region where there is a higher concentration of solvent. For any solution, osmotic pressure is directly proportional to its absolute temperature, and at a constant temperature, it is directly proportional to the solute concentration.
Does pH affect osmosis?
pH is the measurement of the hydrogen ion concentration of a solution. Solutions with a high concentration of hydrogen ions have a low pH, and solutions with a low concentration of H+ ions have a high pH. When both sides are equal in concentration, then osmosis is finished, and equilibrium has been reached.
Which of the following solutions would have the highest osmotic pressure?
Since solution (d) has the highest van’t Hoff factor, it has the highest osmolality, and therefore the largest osmotic pressure.
Which plant has highest osmotic pressure?
halophytes
Which one has the highest osmotic pressure?
Osmotic pressure is a colligative property and depends on the Van’t hoff factor,i.I has the highest value for Al2(SO4)3 as it dissociates to give 5 ions and therefore the osmotic pressure would be highest for solution containing decinormal Al2(SO4)3.
