What is meant by osmolarity?
Osmolarity: The concentration of osmotically active particles in solution, which may be quantitatively expressed in osmoles of solute per liter of solution.
What is difference between concentration and osmolarity?
is that concentration is the act, process or ability of concentrating; the process of becoming concentrated, or the state of being concentrated while osmolarity is (chemistry) the osmotic concentration of a solution, normally expressed as osmoles of solute per litre of solution.
What is osmotic concentration?
Osmotic concentration. Osmotic concentration, formerly known as osmolarity, is the measure of solute concentration, defined as the number of osmoles of solute per litre of solution. The osmolarity of a solution is usually expressed as Osm/L, in the same way that the molarity of a solution is expressed as “M”.
What is meant by osmotic?
the tendency of a fluid, usually water, to pass through a semipermeable membrane into a solution where the solvent concentration is higher, thus equalizing the concentrations of materials on either side of the membrane.
When the osmotic concentration is the same inside and outside the cell?
Isotonic cells have an equal concentration of solutes inside and outside the cell; this equalizes the osmotic pressure on either side of the cell membrane which is a semi-permeable membrane.
What is the osmotic solution?
Osmotic solutions are those solutions which can cause osmosis if separated from solvent by semipermeable membrane . they are of three types- Hypotonic solution, Isotonic solution and Hypertonic solution.
What is the best definition of osmosis?
1 : movement of a solvent (such as water) through a semipermeable membrane (as of a living cell) into a solution of higher solute concentration that tends to equalize the concentrations of solute on the two sides of the membrane.
How does concentration affect osmosis?
Concentration gradient – The movement of osmosis is affected by the concentration gradient; the lower the concentration of the solute within a solvent, the faster osmosis will occur in that solvent. Light and dark – They are also factors of osmosis; since the brighter the light, the faster osmosis takes place.
What is tonicity and osmolarity?
Tonicity is the effective osmolality and is equal to the sum of the concentrations of the solutes which have the capacity to exert an osmotic force across the membrane. The key parts are effective and capacity to exert. The implication is that tonicity is less then osmolality.
