what is osmotoc pressure? explain and derive equation.
Answers
Answer:
From the van't Hoff law or osmotic pressure formula π = (n/V)RT = [Ci]RT, we can see that, besides the gas constant R and the absolute temperature T (not changed in constant condition), the osmotic pressure is proportional to the molar (quantity) concentration.
Question
what is osmotic pressure? explain and derive equation.
Answer
osmotic pressure
Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. It is also defined as the measure of the tendency of a solution to take in pure solvent by osmosis.
